The End

Tony felt his phone buzzing in his pocket as he held Peter with one arm and carried the diaper bag with his other arm.

Pepper had to go to her office for a phone meeting so she left to go do that for a few hours while Tony would stay with Peter.

They were waiting for the elevator to bring them up to their floor but Peter was becoming increasingly whiny by the second. Tony was losing his grip on Peter and couldn’t hoist him up since his other hand was full so he was holding onto the top of Peter’s diaper just hoping that it wouldn’t come off.

Peter was trying to wrap his legs around Tony’s leg but that only made it harder for Tony to walk. “Pete, you need to walk now because I can’t carry you like this”

Peter shook his head as he slowly kept slipping down on Tony’s leg until Tony decided to just place him on the ground of the elevator until he could rearrange the diaper bag.

“Up!” Peter made grabby hands up at Tony as soon as Tony placed him on the floor.

“One sec, Pete. Daddy’s hands are full right now” Tony tried to get the diaper bag strap from off of his arm but it was all tangled and wrapped up. Peter started trying to jump on his foot to reach for Tony but he was still too small to even come close.

“Daddy, wan’ up” Peter whined and continued to try and jump into Tony’s arms.

The elevator doors opened and just as Tony went to walk out, he looked up and saw that it was Steve’s level. Tony sighed in annoyance. “FRIDAY, wrong level. Take us to my floor”

“Boss, Steve Rogers requested to speak with you” FRIDAY supplied so Tony let out another sigh of annoyance. The last thing he wanted to do was to talk to Steve when all he wanted was to get Peter changed and calm him down for the night.

Tony ignored Peter’s whines as he stepped out of the elevator and grabbed onto Tony’s tiny hand instead. “No, daddy! Up!”

Steve walked out from the kitchen. “I’m glad you came, Tony.” Steve looked down at Peter and a gentle smile appeared on his face as he walked closer to the two. He leaned down so he was closer to Peter’s level. “Hello Peter. How are you?”

Peter squeezed Tony’s hand tighter as he turned around to look at Steve. Tony wasn’t sure if Steve was aware of the fact that Peter seemed to no longer be in his teenage mindset anymore so Peter most likely won’t answer Steve’s question.

Peter looked at Steve and pointed to Tony. “Wan’ up”

“He wants me to pick him up but my hands were full, so let me just untangle myself from this diaper bag…” Tony went to go get his arm out of the bag strap when Steve held his arms out for Peter.

“Want me to hold you until Tony can?” Steve asked but Peter shook his head.

“No. Wan’ daddy” Peter tried to explain and point at Tony but Steve looked confused.

“Let steve pick you up until I’m done” Tony said to Peter who then immediately raised his arms up for Steve to hold him while he finished what he was doing.

Steve lifted Peter into his arms and set him on his hip as Peter stuck his thumb in his mouth and laid his head on his shoulder. He would much rather be in Daddy’s arms but this would have to wait until he Daddy came to him.

“So… daddy? He calls you that now?” Steve asked. He tried to ignore the fact that Peter was just in a diaper and the diaper felt really full.

Tony managed to put the bag on the ground and then walk over to Steve. “Yep. He apparently doesn’t know I’m Tony anymore. I’m just daddy now”

Peter saw Tony coming closer to him so he held his arm that didn’t have his thumb in his mouth out to Tony. As Tony took his kid from Steve, Peter made a sound of content that made Tony smile and press a kiss to his temple.

“I think he needs to um, change his diaper” Steve made a face of disgust and pointed to Peter.

Tony rolled his eyes as he walked past him. “I just changed him. He doesn’t need another diaper change yet.”

“Then why does it feel so full?” Steve asked genuinely confused as he followed Tony into the living room where Natasha and Clint were.

“Oh Steve. You have so much to learn,” Tony teased. “That’s just how diapers are.”

Clint sprang up from the couch and walked over to Tony and started poking Peter on the foot. Tony knew that Clint had three kids of his own, he’s not sure how old the youngest is but he’s pretty sure it’s a boy about four years old but he’s not sure.

He just knows that Clint doesn’t get to see his kids a lot so he’s not surprised that the man is just itching to hold Peter. Peter giggled at Clints tickling so Tony offered Peter over. “Wanna hold him, Bird Brain?”

Clints eyes lit up. “Yes! Come here, little guy. Hi Peter. Hi!”

Tony waited for Peter to start crying once he was handed off to Clint but he didn’t which Tony was surprised about. Clint lifted Peter up in the air which had Peter giggling like crazy.

Tony watched the two for a few minutes before Steve was grabbing his arm to get his attention. “What’s up, Cap? Did you want to hold my kid again?”

Steve’s eyes widened. “Your kid? And he’s calling you dad. Are you sure this is healthy, Tony? Is he forgetting that he’s actually fifteen?”

Tony rolled his eyes. This is why he kept Peter away from everyone that wasn’t Pepper. “Yes he’s my kid. I’m changing his diapers and getting peed on so I think I can call him mine. And it’s daddy, Steve. I’m not even sure he can say dad at his age, sounds too old. As for the other thing, I don’t know. I have no way of knowing that for sure”

Steve raised his eyebrows at Tony. “But you have an idea?”

Tony shrugged. “I actually don’t know. I do but it’s just what I’ve noticed, I haven’t done any research or anything”

Tony sat down on the couch arm rest as he watched Peter dance on the ottoman between the couches as Natasha and Clint clapped for him to dance more. The scene brought a smile to Tony’s face.

Steve interrupted that by talking. “What about Bruce? I know he’s been doing some research and testing on it”

Tony sighed. He hated talking about this and thinking about it because he knew that all of this was temporary. Tony knew that Bruce would be able to figure out a cure and how to turn Peter back into his teenage self with the blood samples and working with Cho. Both were science geniuses.

Tony realized that he just wasn’t working hard enough to get Peter changed back into a teen when he was working on it and that if he really wanted Peter to be a teen again he would be working until he found a way to get Peter back but he didn’t since he liked the way things were. He loved it.

He just nodded his head at Steve’s question. “He’s been calling me so I’ll talk to him later.” Tony then stood up and sat on the ottoman that Peter was still dancing on.

Peter turned around when he sensed someone behind him and squealed in excitement at seeing it was his daddy. “Hey, Pete! Are you dancing? Show me your dance”

Peter continued to bounce up and down which consisted of him dancing as he screamed. He started saying something that even Tony couldn’t understand and he was used to baby babbling from Peter.

The adults continued to watch Peter dance until he suddenly stopped and threw up. Peter then sat down on his butt and just sat there.

Steve immediately went to go get some napkins and came back with them. He began cleaning up for Tony while he was handling Peter. “Is he sick?”

“No, it’s just baby vomit. It happens but he’s not sick” Tony pulled the top off of Peter that was now covered in vomit and used the clean part of his shirt to wipe away the vomit on Peter’s chin.

Tony hesitated as he was about to take off Peter’s diaper too since it also got vomit on it but he decided against in seeing as there was an audience watching right now.

“Thanks, Steve.” Tony thanked him for cleaning up the vomit on the ottoman, it wasn’t much but he was still thankful for him to have done that for him. “I’m gonna take him up now.”

Peter climbed off the ottoman and followed Tony over to where the diaper bag was with all the adults following him to say goodbye. Tony held the bag with one hand because he was not about to get tangled in that thing again.

“Bye, Peter” Clint waved bye to Peter and all Tony could think about was if someone ever took Peter away from him and he couldn’t see his kid for months on end, he would go crazy so he really felt bad for Clint.

“Go give Clint a hug bye, Petey” Tony pointed to Clint and Peter then toddled over to Clint and lifted his arms up. Clint wasted no time in scooping Peter off the floor and holding him on his hip as Peter waved at him.

“Bye-bye” Peter said. Clint hugged the toddler then placed him back on the ground. He hated seeing Peter go and it made him miss his kids so much but he knew that Peter was Tony’s kid now.

“Want up?” Tony asked. He looked down at Peter and saw that he had his thumb in his mouth and was nodding so Tony bent down and picked Peter up, holding him on the hip.

He walked into the elevator which took them to his floor and once the elevator doors opened, Tony sighed in relief. He was exhausted and was so ready for bedtime.

That’s when Tony’s phone rang again so he quickly dropped the diaper bag by the couch and used his free hand to pull his phone out of his pocket. “Hello?”

“Tony, I’ve been trying to call you all afternoon” Bruce said into the phone. Tony was scared to hear what Bruce had to say.

“Sorry, Bruce. I was busy with Pete” Tony paused. “Do you have any news?”

Tony unconsciously held his breath as he waited for Bruce to talk. He tried to focus on the heavy weight of Peter on his hip.

“I found a way to change Peter back into a teen” Bruce said really fast. Tony didn’t know why he wasn’t happy about that. “Well, I think I did. Cho and I have developed so many serums but none of them worked. We think this one will and if it does then Peter will be a teen again”

Tony could tell that Bruce was excited about this. He knew he should be too but he couldn’t be.

Tony knew he was going to lose this life he wanted to have with Peter.

“Let’s hope it works then. Thanks for doing this” Tony said sadly. He leaned his head gently against Peter’s and thought that he wasn’t going to be doing this for much longer.

“No problem. I’m confident it’s going to work, Tony. You get to have your teenager back pretty soon,” Bruce laughed happily. “I can come over tomorrow morning at around ten. Does that work for you?”

Tony sat down on the couch and swung Peter’s legs so that he was sitting on his lap with each leg on either side of him. He nodded his head but remembered that Bruce couldn’t see him so he spoke. “Yeah. Yeah, it’s perfect. I’ll Uh, I’ll see you then.”

After Tony hung up the phone he was tempted to throw it but he didn’t. He knew he had to call May and tell her the news. Tell her that Peter would be changing back into a teen again.

To tell her that this was Peter’s last night as a toddler.

Tony hated that. He wished so badly that he had a longer time with Peter. He wants to be with him like this just a little longer but now all he was getting was one more night. Not even a full day.

Tony pressed a kiss to Peter’s head and stood up. He would call May later but right now he was going to enjoy his last night with his baby.

Tony walked with Peter into his bedroom to grab a clean diaper, wipes, diaper rash cream and some clean pyjamas. This used to be Tony’s favourite time of the day, bath time. Now, he hated it.

All tony could think about while he was getting everything ready for Peter after his bath was that this was going to be the very last time he was going to be doing this.

Tony was sitting on his knees on the soft ground while Peter sat on his teddy bear in the corner of his bedroom.

Tony watched him with a sad smile for a few seconds. “Hey, Pete. Come here, you ready for your bath?”

Peter turned around to face Tony with a toothy grin as he nodded his head then crawled over to Tony making grunting noises.

Tony patted his diapered butt, grabbed everything and stood up.

Tony began walking to his own bedroom where he would give Peter his last bath. He was going to try not to think about that so it wouldn’t ruin his last night with Peter but it was going to be extremely hard.

Tony looked back and saw Peter crawling down the hallway as he followed Tony before getting up and running ahead of him, straight into the bathroom.

When Tony walked in there only a few seconds after Peter. He smiled when he saw that Peter was standing there, in the middle of the bathroom with his thumb in his mouth.

When Peter saw Tony walk in, he took his mouth out of his mouth and ran over to his legs to hug them. “Daddy! Baf!”

Tony had already placed everything on the bed so his hands were free to pick Peter up with both hands and blow a raspberry on his tummy. Peter kicked his legs, giggling like crazy until Tony put him down.

As if Peter knew it was his last night being a toddler, he hugged Tony’s legs as Tony filled his bath up for him.

“Come. Let me take your diaper off” Peter stood there so Tony could pull his diaper off and toss it in the corner for now until he can throw it out.

Peter ran around the bathroom and kept screaming excitedly while Tony waited for the bath to fill up. He knew the perfect height for Peter now so he was basically an expert at giving the toddler his baths. A skill that would no longer be needed after tonight.

Once the bath was filled, Tony looked over to where Peter was and found him trying to climb on top of the toilet seat.

“Peter, no. Get down from there” Tony felt his heat sink into his stomach at the sight of Peter climbing up on that since if he were to fall he would bang his head on the hard tile floor. Not good.

Tony quickly got up and grabbed Peter by the underarms, carrying him over to the bath. He lifted him up and placed him in the tub which Peter started squealing about and splashing around.

Tony sat on the floor while he had one hand in the bathtub to splash Peter with. He had a genuine smile on his face since he momentarily forgot about this being the last bath with Peter, he hated that he kept thinking about it but he couldn’t stop.

Tony then looked at Peter’s face because he suddenly stopped laughing and had a serious face. Tony immediately knew it was Peter’s poop face and he did not want him to poop in the tub.

“Peter, are you gonna poo?” Tony asked him with a hint of fear to his voice.

Peter looked up at him and slowly nodded his head so Tony quickly reached in the tub to grab Peter and carried him over to the toilet, getting soaked in the process.

Tony placed Peter on the toilet seat but it was too big for him to leave Peter sitting there otherwise he would fall in so Tony held onto him under his armpits.

Peter whined uncomfortably and Tony understood how uncomfortable this whole thing was for the toddler. Getting taken out of a warm bath to poop in the toilet when he spent the last few weeks doing that in his diaper.

Once Tony was sure Peter was done he picked him and placed him on his feet so he could grab some toilet paper to wipe his butt before placing him back in the bath.

“No!” Peter cried out while he tried to get away from Tony with the toilet paper.

“One second, Peter.” It was hard to do this with a wiggling and wet toddler but Tony managed to wipe Peter’s butt before flushing the toilet and putting him back in the water.

It wouldn’t have been the last bath time with Peter if it didn’t include some sort of poop accident, Tony thought sadly.

Peter crossed his arms and turned his back to Tony in the water. Tony poked him in the back, having no idea why Peter was mad at him.

“Bad daddy” Peter pouted and turned a bit to point at Tony.

“What? Why am I a bad daddy? Because I didn’t let you poop in the bathtub?” Tony sarcastically asked but Peter nodded his head. “What?! Peter no. That’s disgusting.”

Peter kept his back to Tony as he mumbled something that Tony couldn’t understand and Tony really didn’t want Peter to be mad at him for their last night. He would not like that happen.

“Pete, please look at me” Tony tried to think about something that Peter would like to do to try and buy his love for tonight. “Do you want to go down to the lab after bath time?”

Peter turned around to look at Tony and Tony was sure he saw teenage Peter in his eyes for a split second before leaving. Peter clapped his hands together and moved to stand up in the tub so he could dance excitedly.

Tony laughed at his kid and pulled his phone out to take a video of Peter with him giggling. “I wan’ go now”

Tony put his phone down and grabbed the soap bottle. “After bath time, Pete. You still need to have your smelly hair washed”

Tony poked Peter in the stomach causing more giggles to leave the toddlers mouth.

Bath time was quickly finished off since Peter was too eager to sit still. Tony washed his hair and body before picking him out of the tub and wrapping him in a towel.

He cradled Peter in his arms and carried him into his bed where all of the items were to get Peter ready for bed. Although it wasn’t his bedtime yet, Tony still wanted to put him in his pyjamas.

It would be the last time that he dresses Peter in his pyjamas so Tony wanted to take in every second of it but he highly doubted that it would be his last time changing Peter’s diaper since that would be done a bunch more times until Bruce comes over tomorrow morning.

Tony laid Peter on the bed and unwrapped him from his towel as Peter lifted his legs up in the air and started giggling. Tony put a fresh diaper on Peter and dressed him in a two piece pyjama set. It was a lot easier to put him in this since he could get to his diaper a lot easier instead of having to take off his whole onesie.

“You wanna go down to the lab now?” Tony asked, he threw the towel in the corner of his bedroom and turned back to look at Peter who was holding his legs up in the air.

“Uh huh! I wan’ walk!” Peter went to slide off the bed but Tony helped him so he wouldn’t hurt himself. Peter then started toddling in front of Tony as they walked down the hallway towards the living room and then to the elevator.

Tony thought about the next time that he would be going down to his lab with Peter after this would be when Peter is up to his chest, not his kneecap.

It was sad for Tony to think about and how this life he wanted to have so badly with Peter would soon come to an end.

Peter looked up at the ceiling. “F’IDAY! Open door for daddy!”

Peter then turned back around to face Tony with a smile on his face as he held out his hand for Tony to take. Inside the elevator, Tony looked down at Peter and watched as he lifted his thumb into his mouth.

When the elevator doors opened, Tony bent down to lift Peter into his arms and hold him on his hip since he didn’t want Peter to step on anything dangerous or sharp, although Tony keeps his lab very clean… mostly, there’s still a chance of there being sharp pieces on the floor.

Peter was content to sit there, thankfully, so Tony didn’t have to worry about a tantrum happening or little feet getting hurt.

He typed in the code which just so happened to be Peter’s birthday, he changed it about a month after meeting the kid and he didn’t even think twice about doing it.

Peter took his thumb out of his mouth and placed his wet hand on Tony’s face which he winced at but didn’t actually care.

“Woah. Woah” Peter opened his mouth wide and pointed to nothing in particular in the lab.

Tony mirrored his reaction. “Woah, Pete. Wanna go see Dum-E and U?”

Peter nodded his head and looked over to where they usually were in the corner.

Tony thought that was weird because Peter didn’t seem to be in his teenage mind anymore, the fact that he doesn’t even remember that Tony’s name is in fact Tony. So he found it interesting how Peter knew exactly where to look.

Tony walked over there and immediately the bots started making their noises as Dum-E rolled closer to them and lifted his head up taller to see what the small creature that Tony was holding in his arms was.

Peter giggled and reached his hand out to touch the bot. “Dum-E good! Bag go’ dat’”

Tony wasn’t sure what Peter said but he nodded along anyways. “That’s right, Pete.”

“Daddy go bot’ up da’e” Peter said like it was very interesting information and nodded his head along to what he was saying as if it made perfect sense.

“Yes, Petey.” Tony nodded along, having no idea what Peter was saying.

Peter kicked his legs to be put down and Tony looked on the ground to see if he could see anything sharp or dangerous but thankfully there was nothing so he put Peter on the ground.

Peter walked over to Dum-E and tried to sit on the base on the robot but was having trouble doing that because Dum-E kept baking away from the toddler, clearly not happy with someone trying to sit on him.

“Play nice with Peter, Dum-E or I’ll turn you into one of his toys” Tony threatened before turning around to work on some coding for a few minutes. Peter seemed to be busy with the bot anyways so at least he wouldn’t get into anything on that side of the lab.

Peter leaned down and tried to press a wet kiss to Dum-E’s base but the robot rolled away from him which caused Peter to smack his face on the hard ground.

He looked up to see if his daddy saw him but he didn’t so there was no reason to cry. Peter crawled over to Dum-E and patted his base. “I sowwy. I play.”

Dum-E began making a lot of wiring noises as he tried to get away from Peter chasing after him on the ground. Peter laughed because he thought that the bot was playing with him rather than the bot trying to get away from him.

Peter went to stand up but Dum-E grabbed him by his pants and his diaper as he carried him over to Tony.

“Dada!” Peter screamed as he was lifted into the air. Tony was so invested in his work that he totally forgot to check on Peter. He turned around him he heard Peter calling for him and saw that Dum-E was carrying Peter by his pyjama pants on diaper as Peter hung in the air.

“Oh shit!” Tony quickly made his way over to them before Peter was dropped and took him from his bot. “Let go of him, Dum-E”

Once Peter was in his arms, Tony tried to rearrange his diaper and pants now that they were both now half off him while Peter was trying to take a swat at the robot.

“Bad! Bad, Dum-E!” Tony grabbed Peter’s arm as the bot was backing into the corner slowly.

“Peter, no. He was just carrying you over to me. He’s not bad” Tony explained to the toddler, settling him more comfortable on his hip.

Peter looked between his daddy and the bot before nodding and sticking his thumb in his mouth. Tony decided that they were done in the lab because he wanted to talk to Peter about what was going to be happening tomorrow morning before he fell asleep.

“Let’s go upstairs and I’ll make you your bottle then we can watch some cartoons” Tony said to Peter as he went into the elevator and back upstairs.

He held Peter on his hip the whole time he made his bottle and then walked into the living room, putting Peter next to him on the couch so he could talk to him.

“Peter, I need to tell you something important” Tony started. Peter looked at him as he drank from his bottle and Tony wasn’t even sure if Peter was actually listening to him or just staring. “So Bruce is going to come over tomorrow morning to turn you back into your teen self.”

Tony waited for any kind of reaction but he got nothing. He continued. “He found a way to change you back so after tomorrow you’re going to go back into a fifteen year old again, baby.”

Tony wondered if he’d be calling Peter ‘baby’ once he’s fifteen again. The nickname only started after Peter got de-aged so he wondered if it would stick.

He tried not to sound so sad as he explained to Peter what would be happening because in all honesty, he didn’t want it to be happening and he knew that Peter deserved to live his life properly but he was scared. He didn’t want Peter to grow up and never speak to him again or never be able to do everything that he does with Peter now. He loves his life how it is now but all that was soon coming to an end.

Peter still continued to suck on his bottle as he stared at Tony and it was frustrating because Tony had no idea if Peter was understanding anything he was saying.

“Peter, are you listening to daddy?” Tony tried and Peter nodded his head. “Do you understand me?”

Peter nodded again which Tony was grateful for. “What am I saying, Pete?”

Peter took his bottle out of his mouth and tried to hand it to Tony. “Wan’ more milk daddy”

Tony grabbed the empty bottle feeling defeated.

Peter had no idea what he was saying and there was no way to make him understand.

Sighing, Tony stood up to go get Peter more milk in his bottle. When he returned he passed the bottle to Peter and sank into the couch.

Tony covered his face with his hands but he then felt someone crawling on his lap and moving around before settling on him. Tony smiled at the scene and saw Peter casually sitting on his lap with his back to him as he drank his bottle.

He pointed at the tv and whined, he didn’t use any words but Tony knew he wanted his cartoons on.

“How about we go watch them in my bed, buddy? Do you wanna sleep with daddy tonight?” Tony asked as he pressed a kiss to Peter’s hair. He felt the toddler nod his head so Tony lifted him up and carried Peter into his bedroom, gently placing him on the bed before lying down next to him.

Peter laid his head on Tony’s shoulder as Tony flipped through the channels until landing on a cartoon that Peter liked to watch.

Tony wasn’t sure why Peter liked watching this show so much, In The Night Garden, Tony wasn’t sure what Peter liked about it so much but he had to admit that it was relaxing. Or maybe that was only because Tony was content right now with his baby with him.

Peter took his bottle out of his mouth and replaced it with his thumb as he slowly started to fall asleep.

Tony laid there for a few more minutes but he knew that he had to get up and call May to tell her about what was happening tomorrow.

He slowly got out of bed and looked at his baby sleeping there. Peter had his arm above his head with his other hand in his mouth, sucking on his thumb.

Tony wished he could stay in this moment forever.

As much as he wanted to stay, Tony left and went into the living room to call May.

She answered on the third ring. “Hi Tony. Is Peter okay?”

Tony laid his head in his hands. “Yeah, Pete's fine. I’m just calling because Uh, Bruce, he thinks he found a way to change Peter back into a teen and it’s gonna work. He’s pretty confident it’s gonna work so uh, he’s coming over tomorrow morning and I’m just telling you because I know that you’d wanna be here for that”

May was silent for a few seconds before letting out an excited laugh. “Yes! Yes! I’ll be there. Oh, Tony! Finally! I’m gonna get my boy back. I’m gonna get Peter back”

Tony couldn’t say anything. He hated this so much.

“I’ll be there, Tony. I can’t wait! Thank you for watching him while he was… well, you know, a baby” May sounded really happy and Tony wanted to hang up on her. “But don’t worry, I’ll be taking him out of your hair once he can actually wash his own hair on his own and actually use a toilet instead of diapers.”

“I enjoyed watching him, May. It wasn’t like I didn’t enjoy it” Tony said annoyed. He wanted to say so much more but he didn’t.

“Thank you for that, Tony. I’ll see you tomorrow” May then hung up the phone and for the first time in…months, Tony felt tears rush to his eyes so he put his head in his hands to try and stop them from falling but he knew it was too late.

He had no idea why he was having so much trouble dealing with the fact that Peter was going to be a teen this time tomorrow. He just felt so… happy these last few weeks.

The elevator doors opened and the sound of heels were heard walking towards him. Tony didn’t even bother to make himself look presentable for Pepper because he knows that she’s seen him at his worse.

She walked closer to him then gasped. “Tony? Where’s Peter? What’s wrong?”

Tony lifted his head up and let out a laugh. “I’m an idiot. I don’t know why I’m fucking crying over this”

Pepper put her bag down and sat next to Tony on the couch. She looked at him concerned and ran a comforting hand down his back. “Where’s Peter?”

“He’s sleeping in my room. He’s fine”

Pepper looked at him with concern written all over her face. “Why are you crying? What’s going on?”

“Bruce is coming over tomorrow morning,” Tony started. “He found a way to change Peter back into a teen”

Pepper nodded in understanding. “You don’t want that, do you?”

Tony laughed. “I want to. I want to want to want it. But I don’t”

Pepper only nodded. She knew Tony was happier ever since Peter got de-aged and he really moved into the role as a father quickly and was doing a good job at it.

“I don’t know why I’m crying over it. Pete’s made me soft” Tony laughed weakly then let out a shaky breath. “I’m being selfish. It’s selfish of me to want this life with him as my kid, I know it is but I can’t seem to care. As long as he’s happy. I tried talking to him today, Pep, about-about tomorrow but he didn’t even care.”

Pepper put her hand on Tony’s knee and squeezed it. “I know this is hard for you, Tony. I know. And I’m sorry that it has to be this way but I think- I think you need to go and enjoy your time with him now before Bruce gets here tomorrow”

Tony took a few seconds to nod his head. He didn’t say anything as he stood up and walked back into his bedroom to go see Peter but when he walked into the room, Peter was sitting up in bed and drinking his bottle.

When he saw Tony he reached his hand out for him and let out a whine. “Daddy”

“I’m here, baby. Daddy’s here” Tony sat down on the bed and pulled Peter into his arms. He felt that his diaper was full so he stood up, still holding onto Peter and went to grab a diaper and some wipes.

He then tried to lay Peter down on the bed but Peter cling tightly onto him. “No daddy. No go”

“I’m not going anywhere, baby. I just need to change your diaper” Tony said softly into Peter’s ear.

Peter then let go of Tony and let himself be placed on the bed while Tony pulled his pants down to get access to his diaper.

Peter watched Tony as he wiped him clean then put a new diaper on him followed by his pants being pulled back on.

When Tony picked Peter up and lay down with him in the bed, Peter went to poke Tony in the eye but Tony moved his head so Peter couldn’t.

“Daddy sad?” Peter asked confused.

Tony nodded his head. “Yeah, baby. I am. Remember what I talked to you about earlier today? Well that makes me really sad, baby. But even when you’re bigger, you’re still gonna come see daddy, right?”

Peter nodded his head and laid himself on Tony’s chest. “Uh huh. I stay wif’ you”

Tony put on hand on Peter’s diapered butt and his other hand on Peter’s back. “Promise me?”

“P’omise daddy” Peter let out a tiny sigh and Tony held him until he felt Peter drift off into sleep followed by himself.

.
.
.

When Tony woke up, he first felt the sun shining on his face and causing him to moan in annoyance then turn around. The second thing he felt, or smelled, was a smelly butt in his face.

That got Tony sitting up in bed and opening his eyes. He saw that Peter had his butt in Tony’s face and half his pyjamas were down making his sagging diaper very noticeable.

Tony flopped his head back onto the pillow, wishing he could deal with this in another hour but he didn’t want Peter to get another diaper rash.

Tony then remembered what today was.

In only a few hours Peter would be a teen again and probably in the car with May going back to his apartment building.

Tony checked the time on the nightstand clock and saw that it was 8:14am meaning that Bruce would be at the tower in just under two hours.

Pushing those thoughts out of his mind, Tony ignored the smell and gently shook Peter awake who immediately woke up and smiled at Tony after giving a little stretch.

“Hey, bud. Good morning” Tony smiled at Peter and rubbed his bare stomach.

Peter giggled and rolled away from Tony.

“You need your diaper changed, you smelly butt” Tony teased as he was already getting off the bed to grab some wipes, a diaper and diaper rash cream.

Peter sat up in bed and shook his head. “Uh Uh. You smelly daddy”

Tony shook his head and patted the bed in front of him for Peter to come lie down. “I’m not the one who pooped in my diaper”

Peter crawled over to Tony and lifted his legs up as he still shook his head. “Not me. Not poop”

Tony pulled Peter’s pants off and then pulled down the front straps of his diaper seeing that Peter in fact did poo in his diaper. “Then what’s all this, Pete? Pee?”

Peter tried to look at the mess but Tony was holding his legs up with one hand and wiping Peter’s bum with the other.

The smell caused Tony to gag about three times and get pooped smeared on his hand but after a lot of wipes and wiping, Peter was clean.

Tony wanted to let his diapered area breathe for a bit so he lifted him off the bed and went into the bathroom himself to wash his hands and brush his teeth while Peter walked around the bathroom waiting for him.

“Let’s go get you dressed now” Tony said and reached for Peter’s hand.

They both made their way into Peter’s bedroom, with Peter immediately running over to his teddy bear to sit on while Tony found what Peter would be wearing for the remainder of his time as a baby.

He pulled out a pair of harem pants that were green and had little black dinosaurs on them as well as a white T-shirt with a crocodile on it.

“Peter, let’s get you dressed now” Tony looked over at Peter who had his back to him like he usually did when he sat on his teddy bear in the corner.

Peter shook his head. “No. Wan’ stay na’ed”

“You can’t stay naked. People are coming over today, bud.” Tony reached over to grab a new diaper since he forgot the other stuff in his room. He also grabbed the diaper rash cream seeing as though Peter was a bit red between his legs. “Come lie down in front of me”

Peter shook his head but got up anyways and slowly walked towards Tony before lying down. Tony pulled his pyjama top off of him and began putting a generous amount of cream on his bum and penis before putting a diaper on him and dressing him in his clothes.

“All done!” Peter clapped his hands together.

“All done!” Tony repeated after him and used his clean hand to tickle his stomach before getting up to wash his hands.

While he was washing his hands, Peter sat on his foot and wrapped his arms around his leg. “Daddy I hun’gy”

“Let’s go eat some breakfast then, what do you wanna eat, baby?” Tony lifted Peter up, setting him on his hip as they walked into the kitchen.

“‘Nana” Peter pointed to the stack of fruits sitting in a bowl on the counter so Tony placed Peter in his high chair and began cutting up his banana. He then gave it to Peter to eat while he got some more food for Peter. Some dry Cheerios in a bowl along with more fruits.

While Peter was eating his foot, Tony made his coffee and poured himself his own bowl of Cheerios but with milk. As he was eating his cereal in front of Peter, Peter started reaching an arm out for his bowl.

“I wan’” Peter said.

Tony pointed to his high chair that was still full of food. “You have your own food”

Peter shook his head. “No wan’ you!”

“You want a bite of my cereal?” Tony asked and Peter nodded his head so Tony held his spoon out to feed Peter.

He wasn’t sure if the spoon would even fit in Peter’s mouth but he would try. Peter held his mouth open and Tony tried his best to fit the spoon inside but his mouth was just too small so it spilled down onto his high chair tray.

“Hmm! ‘Ummy” Peter nodded his head at Tony’s cereal then went back to eating his own food.

Tony laughed at how cute his kid is before finishing off his own cereal.

Pepper walked out of the elevator and Tony turned to look at her. If it was anyone else he would have felt embarrassed about crying in front of them just a few hours before but he didn’t care since it was only Pepper.

“Hi Peter! What are you eating?” Pepper asked. She ignored Tony and walked right up to Peter in his high chair.

Peter grabbed a piece of his chopped up banana. “Nana! Ummy!”

“That looks so good, Peter” Pepper looked at the disgusting mashed up food on the high chair tray then turned to Tony. “Is May coming?”

Tony nodded, feeling his mood drop.

As if on cue, the elevator doors opened revealing both May and Bruce as they walked out of the elevator. May looked extremely happy which Tony looked away from and focused his attention on Peter.

Pepper squeezed Tony’s shoulder before walking over to May and Bruce.

Tony ignored their conversation as he grabbed a baby fork and started feeding Peter himself. Peter was curious as to who the new people in the living room were but Tony tried to distract him from it.

Tony was trying to enjoy his last bit of time with Peter as a toddler he had left.

“Hi Peter! Are you eating… what is he eating?” May asked. Tony had to admit that the food on Peter’s tray now looked disgusting.

“Well it was bananas and blueberries at one point” Tony answered, not turning around to face May. “Do you want more, Petey?”

Peter nodded his head which Tony was grateful for so he grabbed another banana and started to cut it up. May took a seat next to Peter and tried to get his attention but Peter was more focused on Tony.

When Tony sat back down with Peter’s chopped up banana, Peter squealed. “‘Nana daddy!”

“Yeah! Look, Hmm!” Tony began to feed Peter his bananas, he ignored May but she eventually stood up and walked back into the living room.

He didn’t want to talk to the women who would be taking his kid away from him in only a matter of hours.

Pepper walked up to Tony and squeezed his shoulder. “Are you ready? Bruce is waiting”

Tony slowly nodded his head. He hated this all so much.

He grabbed a wet cloth and wiped Peter’s face off then lifted him out of his high chair, thinking about how that would be the last time he ever does that.

He placed Peter on his hip and walked over to where May and Bruce were.

Tony sat down on the couch with Peter in his lap as he held onto him tightly, not wanting to let go. “Alright. How does this work?”

Bruce held up a fairly big needle. “I inject this into his arm and immediately he will start growing back into his normal size of a fifteen year old”

Tony nodded his head. “How long will the process take?”

“It should only take about one to two minutes” Bruce explained.

May cut in. “Will it hurt him?”

“It shouldn’t but I have no way of knowing for sure. Either way it’ll be quick” Bruce held up the needle and walked closer to Tony. “You should take off his clothes just because I don’t think he will age back up with them still fitting him… and I know how uncomfortable it is to get your clothes ripped off of you like that”

Tony nodded as he began to pull the top over Peter’s head and tugging his pants off so that he was just in a diaper.

“I’m gonna do it now, Tony, so can you lay him on the couch” Bruce asked. He walked closer to Tony and Peter with the needle but Tony stopped him.

“Wait! Just… wait. I just need to take him in one last time before he’s not this small anymore” Tony turned Peter around in his lap and pressed a kiss to his chubby cheek.

He thought about the first time he saw Peter like this and how confused they both were when he had to first change Peter’s diaper.

Tony hugged Peter close to his chest. “I love you so much, Peter. No matter what age you are. Daddy loves you”

Peter looked up at Tony confused. “Daddy?”

“Okay… I’m ready” Tony told Bruce. He stood up and laid Peter on the couch as Bruce stepped towards Peter with the needle.

May and Pepper both watched nervously in the background.

“It’s okay, Peter. I’m here” Tony calmed him. “Daddy’s here”

Bruce injected the needle into Peter’s leg resulting in Peter letting out a loud cry. Peter tried to reach out for Tony but Bruce pulled Tony away as they waited for the injection to reverse the effects.

Tony subconsciously held his breath as they waited for Peter to age back up. He listened to Peter cry out for him and try to reach for him but he didn’t do anything.

Tony wasn’t sure what he was expecting but what he wasn’t expecting was for nothing to happen… nothing. Absolutely nothing at all.

They all waited one minute then two then three and at minute four, Tony turned to Bruce.

“Is this supposed to happen?” Tony asked.

Bruce shook his head and started digging through his file of papers. “No. No, this is not supposed to happen. It was supposed to work. I-I tested this out multiple times to make it perfect. It should have worked”

Tony walked up behind Bruce and tried to read some of his notes. He only understood half of what was written but he had an idea of where Bruce was going with this.

Bruce looked through his papers and started doing a bunch of calculations while May started freaking out.

“What’s going on?! Is it not working? This was supposed to work, Tony. What’s going on?” May asked as she ran her hand through her hair.

Peter was still crying on the couch and screaming for his daddy but Tony ignored him in case touching him would cause any problems.

“I don’t know, May. It clearly didn’t work but I don’t know” Tony saw that Pepper was trying to calm May down as Tony walked over to where Bruce was standing in the corner of the living room, holding up a bunch of papers.

“What’s going on, Bruce. Talk to me.” Tony asked quietly.

Bruce put the papers down and looked at Tony with so much defeat on his face. “I’m sorry, Tony. I’m so sorry. I tried, I really did and this was the only thing that worked. Well, I thought it worked but it obviously didn’t.”

Tony didn’t know what to say.

He was at a loss. He couldn’t be happy even though he wanted this so badly. He felt horrible for wishing it.

“It didn’t work” Tony said.

“It didn’t work” Bruce repeated in confirmation.

“He’s stuck as a two year old now” Tony wasn’t sure if he was asking a question or not but Bruce responded anyways.

“Yes. He’s stuck as a two year old” Bruce confirmed.

Tony let out a shaky breath and ran his hands through his hair. He began walking over to Peter so he could stop his baby from crying out in fear and pain for him.

“It’s okay, Peter. I’m here now. Daddy’s here” Tony began rocking Peter back and forth in his arms while he tried to get Peter to stop crying.

May walked up to him. “What’s going on, Tony?”

“It didn’t work, May. There’s nothing else we can do. He’s stuck like this” Tony explained. He was feeling a lot more calmer about the whole situation now.

May threw his arms up in the air. “What the fuck! So what now, he stays as a two year old for… forever?!”

Bruce walked up to Tony with a much smaller needle. “There’s nothing I can do to change him back into a teen but I am going to run one last blood test.” Bruce said as he stuck the needle into Peter’s leg, causing Peter to let out another loud cry.

Bruce took the blood he needed and then placed the needle in a bag before grabbing his stuff and leaving. Tony knew he was going into the lab that he had here at the tower to work.

“What am I supposed to do now? I can’t look after Peter if he’s two years old! This was supposed to be temporary” May started pacing around the living room as Tony rocked Peter back and forth to calm him down.

“I’ve been doing it this whole time so I’ll continue to look after him, May” Tony said. He wasn’t asking because he would fight for Peter if May decided to say no to him. And he would put up one hell of a fight.

“You can’t take care of him permanently, Tony. This was only a temporary thing that you were okay with because you saw an end. There is no end now. This-this is it. This is a forever thing now” May started to scream to which Tony backed away from so Peter wouldn’t start crying again.

“May, we will all figure out what the next step is from here but I think for now it’s best if Tony takes care of him like he has been doing this whole time” Pepper cut in to say. Tony was extremely grateful for her.

May sighed and sat on the couch. “I just- I just don’t know what to do”

Peter was now sadly hiccuping in Tony’s arms so Tony bounced him as he spoke. “I’m keeping Peter with me. We’ll figure everything else out later”

May nodded her head as the elevator doors opened with Bruce walking out with a determined look on his face. “Okay so, I did a few tests on Peter’s blood and compared them to the blood sample I took from him when he first ended up like this and basically Peter has been slowing growing this whole time only we never noticed because it was at the rate of an actual two year old”

May looked confused. “Wait… I did notice that he looked a bit bigger than before”

Bruce nodded. “Exactly. Peter will eventually be a fifteen year old again but he’s going to have to grow up again. He basically gets a second chance at life”

May stood up as she tried to wrap her head around everything. “Wait… so Peter is going to have to grow up… again? For a second time?”

Bruce nodded. “Yes. That’s right”

Tony couldn’t help at smile at that. Peter was going to get a second chance at life but this time with Tony as his dad.
