My Peter

Tony placed Peter on the living room floor when he got back to their floor.

It was close to Peter’s bedtime but the kid didn’t look tired at all, he actually looked wide awake with lots of energy and that was no doubt to the excitement of being with all the avengers downstairs.

Tony almost got whiplash from how easily Peter’s emotions could change so easily. From crying to happy in the blink of an eye.

They all loved him which was expected but now Tony just hoped that they wouldn’t be trying to steal him because no way would Tony allow that.

Which is why right now Tony was alone with Peter instead of asking someone to watch him for a few minutes while he showered.

Tony always showered after Peter was in bed asleep but now Tony has to shower and Peter was wide awake with no hope in him going to bed anytime soon. He could have asked Steve or someone to watch Peter but then that would lead them to thinking that they could hang out with Peter whenever they wanted and that was definitely not gonna happen.

Tony bent down so that he was closer to Peter’s level on the ground “Pete, I’m gonna go shower now and I’ll only be a few minutes but I want you to stay here”

Peter didn’t look up at Tony and showed that he heard him so Tony gently lifted up Peter’s chin which caused the kid to giggle “Daddy”

Tony’s heart burst when Peter said that. It was his favourite sound in the whole world because it always made him feel like the actual kids father and the way Peter said it was too cute.

“Yeah, Pete?”

Peter didn’t say anything else but he grabbed one of his toys and put it in his mouth and began to suck on it. Tony laughed at him softly before speaking again “Pete, I’m gonna go shower but I’ll be right back. I want you to stay here and play with your toys”

Peter nodded his head as he continued to suck on his toy. Tony stared at him for a few seconds trying to think if Peter was even listening to him or if the kid was actually gonna stay. He had to hope for the best because it wasn’t like he could bring Peter into the shower with him. Peter would have to stay here.

Before Tony left he turned on the tv and played some baby cartoons that Peter really seemed to enjoy.

Giving one last glance at Peter before leaving, Tony left and just hoped that the toy and the tv could keep Peter entertained long enough for Tony to get back.

Peter continued to suck on his toy until he got bored of it. He couldn’t remember if daddy fed him or not but he was definitely hungry.

“Daddy?” Peter stood up and looked for Tony but he couldn’t see the man anywhere. Why did daddy just leave him like that?

Just as Peter was about to go look for Tony the tv caught his attention because the big blue bird and the orange fox were jumping and dancing around so Peter decided to join them.

“Big bi’d!” Peter said excitedly, trying to reach for him on the tv. Peter began bouncing on his feet like all babies do when you tell them to dance.

After only a few minutes the hunger feeling was back in Peter’s stomach and he really wanted his daddy to come back to him and feed him but he wasn’t here right now and Peter was hungry so he was gonna have to feed himself.

He waddled into the kitchen and tried to find something to eat. The only problem was that Peter couldn’t reach anything. He was too small to even grab anything in the fridge so he would have to settle on the cabinets and hope that there was food in there.

Peter opened up the closest one to him and sat down to start pulling things out. He pulled out some boring looking type foods until he found some peanut butter.

Peter made a sound of excitement as he dropped the container on his lap and tried to open it. It seemed like his spider power were gone at the moment but he didn’t really feel too upset by that. Tony would come soon and open it for him.

As Peter waited for Tony to show up he began to look for more foods to eat, well foods that he could actually reach. He opened up another cabinet and found all the cereals and he remembers the last time he tried to make himself a bowl of cereal and how that turned out. He managed to get all the cereal all over the floor instead of in the actual bowl.

Peter that that maybe if he if he just ate it out of he box then that would be easier and he wouldn’t make a mess.

He grabbed the box of fruit loops and stuck his chubby hand inside the box then pulled out a handful of them. There was only about five pieces of fruit loops in his hand because his hand was so tiny so he decided to dump the box in the floor. He would be eating them all anyways so then Tony wouldn’t find out.

Peter began to eat some of the fruit loops but he didn’t get to finish them all because he just didn’t want anymore but there was still so much on the floor and there was no way he could get it back in the box. He did the only thing he could think of.

Shove them in his diaper.

Peter started to pick all the fruit loops off the floor and open the front part of his diaper so he could shove them down there and that way Tony wouldn’t find them. Perfect plan.

After all the fruit loops were off the floor and in his diaper, Peter walked back to the peanut butter jar.

Maybe if he tried to drop it from somewhere high then he would be able to open it. But there was nowhere for him to drop it off of. It was so annoying to be his tiny sometimes but he really liked that Tony was always there for him so maybe he liked being this small. Maybe he could get used to it.

Peter tried to open the peanut butter jar again and this time he actually managed to open it which was good because there inside was the yummy looking peanut butter just waiting to get eaten.

Peter stuck his hand inside the jar and grabbed a bunch of it before shoving his hand in his mouth to eat it. It was so good. Better than he remembers it tasting for some reason.

Before Peter knew it, he was covered in peanut butter. The front of his pants had it all over so he put the jar down and tried to take off his pants which was actually a struggle because usually Tony did that for him but he did it this time. Once his pants were off and he was just in a diaper and a T-shirt, Peter was gonna stop eating the peanut butter but he couldn’t. It was too good.

It was also kinda fun to rub all over his legs and the floor as if it were cream, it kinda was just edible cream.

Oh no, Peter definitely got carried away because now looking at himself and the floor... there was peanut butter everywhere. There was no way he could clean this up himself and he didn’t want daddy to be mad at him but if he asked maybe Steve to come help him then Tony wouldn’t find out.

Peter tried to clean the floor off with his pants but there was just too much so he picked up his jar and walked to the elevator.

He knew how to get to Steve’s floor and once he made it there, he walked out and into the living room where everybody still was. Well, only Steve, Sam and Clint.

When Peter arrived holding the jar in his hand and covered in peanut butter wearing nothing but a diaper and a shirt, they all looked surprised to see him but then they were laughing.

“S’eve, help me c’ean” Peter asked Steve. He didn’t understand why they were all laughing at him.

Steve looked down at him and smiled “Hey, Peter. Where’s Tony?”

Peter looked at him confused “I don’ know”

Steve now looked a little scared too because it wasn’t like Tony to just leave Peter like that.

Clint walked over to Peter and poked him in the stomach causing him to giggle “How did you manage to make such a mess?”

“I was hung’y so me mak’ food coz’ daddy gon’“ Peter explained but only Clint really understood what Peter said since he went through the whole baby talk phase and was still kinda going through it with his youngest.

Clint noticed that Peters diaper was sagging too meaning that he hadn’t had a change in awhile so he was starting to get really worried about Tony since it wasn’t like the man at all to leave Peter “And your daddy just left?”

Peter nodded “Uh huh”

“Looks like he’s a serious need of a new diaper” Sam pointed out. They all looked at Peter and expected him to get embarrassed but he just looked at Sam and didn’t react. “You seem the best qualified to change him, Clint, so I suggest you do”

Clint looked at Peter’s sagging diaper but shook his head “I don’t even know where his diapers are so how am I supposed to change him?”

“Well, we need to go find Tony and see if he’s okay because he wouldn’t just leave Peter” Steve stood up and began walking to the elevator with Peter running after him. Peter raised his arms up and demanded to he carried by Steve which Steve happily accepted.

Sam and Clint followed along as well and then they went up to Tony’s floor.

When Tony got out of the shower and started making his way into the living room where he left Peter he was starting to get a little bit scared that there was no baby sounds coming from the carpet.

Tony walked into the living room and found no Peter there “Peter?”

No answer.

Now Tony was starting to freak out “Peter? Bud, where are you?”

Tony made his way into the kitchen and found the mess made by Peter on the ground along with his pants there.

“What the fuck” Tony said. He bent down expecting to get a whiff of the smell of poop because that’s what it looked like but then he smelt peanut butter.

Just as Tony was about to start dreaming out and put the tower on lock down until he found his kid, the elevator doors opened and immediately came the baby sounds that came from Peter.

Tony walked towards the sounds and was surprised to see Steve holding Peter who was covered in peanut butter and had only a diaper and a shirt on followed by Sam and Clint.

“What are you guys doing with Peter?” Tony asked making his way over to Steve who had his kid in his arms.

Peter reached for him “Daddy!”

Steve explained as he handed Peter over to Tony “We thought you were hurt or something”

“Why would I be hurt?” Tony asked Steve confused then looked at Peter “What happened to you?”

Peter cut Steve off “I was hung’y so me mak’ food”

“Why didn’t you wait for me?” Tony asked him. The feeling of Peter being okay and back in his arms again was really calming.

“I don’ know whe’e daddy wen’” Peter explained and shrugged his shoulders.

“I told you, Pete-“

Steve cut Tony off “Peter just came down covered in peanut butter and his diaper was all saggy so we just thought something happened to you”

“I was in the shower” Tony explained. Now he knew that he wasn’t even able to take a shower himself unless Peter was sleeping.

“So you were just in the shower then?” Clint asked.

Tony nodded. “Yes you idiots”

“We wasted a trip for no reason then” Sam said then him and Clint went back in the elevator and left.

“Well, thanks for helping bring him back up” Tony said “I gotta go clean him up now”

Tony poked Peter in the stomach like Clint did before and Peter giggled then leaned his head on Tony’s shoulder.

“I’m gonna go give him a bath now” Tony bounced Peter on his hip “Thanks for Uh, coming up here”

“Do you want me to help you with him?” Steve asked and Tony just looked at him. He was trying to decide if he wanted the help of maybe just someone to talk to that could actually respond since it’s been awhile hanging out with Peter in a toddler form for awhile but Tony decided not to. He liked being with Peter and only Peter.

It wasn’t like he didn’t like being with the kid, he loved it and he especially loved bath times so he decided not to “Thanks but I’ve got it”

Steve nodded. He guessed that Peter didn’t want anyone seeing him naked except for Tony even if he was just in a toddler body.

“If you need anything I’ll be downstairs” Steve said before going into the elevator and leaving.

Tony turned and started walking with Peter in his hip into his bedroom to have a bath.

“I see you’ve been quite busy while I was in the shower” Tony said, Peter was giggling on about something that Tony had no clue about.

He went into his bedroom and then the bathroom that was attached to it. He could have gave Peter a bath in his own bathroom like he usually did but the one in Tony’s bathroom was bigger and more easy for Tony to sit down and wash him without breaking his back.

Tony placed Peter on the floor and sat himself down on the bathroom tub step to start filling up the water. While the water was filling up he could take off Peter’s clothes “Lie down in front of me, Pete”

Peter turned around from where he was looking in the toilet for some reason and walked over to Tony, lying down in front of the man like he was asked.

“You’re lucky this is just peanut butter and not something else otherwise I would have to get a whole new Peter” Tony joked as he rolled up the peanut butter shirt and started undoing the diaper tabs.

“New Pe’er?” Peter asked in a small voice looking up at Tony with curious eyes.

Tony didn’t have time to answer because he pulled down the front of Peter’s diaper and was surprised to see what was in his diaper.

“What the fu- Pete, What is this?” Tony asked Peter who was just laughing and trying to kick his legs away.

Tony thought that Peter may have pooped out whatever the colourful things were but he picked one off of Peter’s thigh and saw that they were fruit loops, the kid had put fruit loops in his diaper!

“Pete,” Tony laughed “What is this?”

Peter giggled again and tried to roll away and Tony let him crawl away a little bit and as he was crawling away Tony saw all the fruit loops stuck to his butt so he reached forwards and pulled Peter closer to him “Where do you think you’re going, Mr?”

Tony stood Peter up in front of him and used the diaper to wipe off most of the fruit loops and then tugged the child’s shirt off.

“Daddy! Daddy!” Peter said excitedly for no apparent reason.

The sound alone of Peter calling him that made Tony burst into a smile “Yeah, Pete, I’m your dad, bud”

Tony held Peter with one hand as he turned around to shut the water off. He left the water running a little bit too long but he guessed that it was fine since he didn’t add any bubbles into it.

“Lift your arms up” Tony said and Peter did excitedly. Tony picked Peter up and placed him in the bath tub.

“I wan’ toys!” Peter said. He was still standing up in the bath and the water was so high on him in the bath that it went all the way up to his waist.

Thankfully Tony had bought Peter some bath toys along with some more diapers since he went through those faster than he expected.

“I got you some, bud” Tony turned around and quickly grabbed the toys under the sink for Peter. He was only looking away from Peter for less than five seconds because anything could happen when it came to Peter and especially with him in the bath. Tony didn’t want to take any chances.

“Ducky!” Peter made grabby hands for one of the bath toys Tony was holding in his hands so Tony placed it in the bath.

Tony noticed that Peter was still standing “Why don’t you sit down, it’ll be a lot more fun”

Peter shook his head “Too deep”

“It’s not deep, bud, plus I’ll be here if you need me” Tony gently put his hands on Peters arms and tried to make him sit but Peter let out a whine “Alright you do you”

Peter seemed to think about it before he sat down in the bath and Tony could have laughed at Peter’s face at first because it looked funny how scared he was but then when he realized he was okay he smiled.

The rest of the bath was spent with Peter playing with his ducks and asking Tony to come in with him do they could play together but Tony said maybe another time. He thought about taking Peter to a beach near here but all the beaches would be too cold so maybe they could go somewhere else?

Until he could figure out how to get Peter back to a teenager, Tony was kinda getting used to the dad life with a toddler. It was a life he never expected to have to get used to before but he loved it anyways. Part of him was sad that he wouldn’t be able to care for Peter forever like this but at least he would still have Peter in his life as a teen. Hopefully. If Peter still wanted him.

Tony tried to push away those thoughts because he was with toddler Peter right now and that’s the Peter that needed him.

Tony washed Peter with soap everywhere making sure that he was fresh and clean and he made sure to wash his diaper area a lot because of the fruit loop incident that Tony would definitely be telling Peter about when he got big again. If he didn’t already remember.

“Are you tired, buddy?” Tony asked Peter as he lifted him up and out of the bath. He laid him down on the towel on the bathroom rug and started to dry him off.

Peter responded by rubbing his tiny fist on his eye which was extremely cute and made Tony want to pick Peter up and hug and kiss him.

Tony finished drying Peter off then he wrapped him in the towel and picked him up, cuddling him to his chest. He had to walk to Peter’s bedroom to get the diapers and pyjamas but he wanted Peter to sleep with him tonight because it actually helped him sleep better and actually fall asleep knowing that Peter was safe and right next to him.

Tony grabbed everything he needed and walked back to his bedroom, placing Peter on the bed and opening his towel.

He looked down at his kid who was practically falling asleep right there on the bed. Tony couldn’t help but smile fondly at his kid. It was so different to see Peter this small but he was still his kid, he was still Peter.

Tony grabbed the diaper rash cream and put some on his finger so he could rub it on Peter’s butt and around his penis to prevent another diaper rash from happening. After that he wiped his hands and put a clean diaper on him.

Peter was looking up at Tony with half opened eyes and then he stuck his thumb into his mouth so Tony looked around his bedroom to see if he could find his pacifier and there it was right on his bed so he reached over to grab it and went to plop it in Peter’s mouth.

Peter shook his head so he could keep sucking on his thumb but Tony gently removed his thumb from his mouth and replaced it with the pacifier.

Tony held his breath unknowingly as Peter scrunched his face up as if he was gonna cry but then he relaxed started sucking on his pacifier now. Tony let out the breath he didn’t know he was holding and grabbed the pyjamas to put on the kid.

The pyjamas were Iron Man ones which Tony smirked as he put them on Peter.

“I’m gonna be right back” Tony whispered quietly to Peter as he left the kid lying on the bed so he could change and brush his teeth.

When he came back into the bedroom, Peter was still lying down on the bed but he was awake fully now. When his eyes landed on Tony he made grabby hands for the man.

“Come here, Pete” Tony lifted Peter up and cuddled him to his chest. This one his favourite time of the day when Peter was extra cuddly and smelt really good. Not that he didn’t smell good any other time but a lot of the time he did smell like a mixture of baby and diaper so this was a definitely step up from that.

Tony peeled back the blankets and crawled into them. Today was definitely a big day for Peter and now it was all starting to catch up to him which Tony wasn’t complaining. He was tired as well and he knew he would actually be falling asleep with Peter here.

He laid Peter next to him and brought the blankets up so that it was covering them. Tony had to reach over and throw some pillows on the other side of Peter so he didn’t roll off on that side.

When he laid back down, Peter crawled over so that he was sleeping on top of Tony’s chest. Tony relaxed into the bed and kept his hand on Peter’s now clean diapered butt as he closed his eyes.

He could feel Peter’s tiny breaths coming out of his mouth on his neck.

It didn’t take long for them to drift off into a deep sleep together.
