Messy, little one

Peter was in a bad mood.

Tony has no idea what happened to his cuddly child from last night but he doesn’t like this Peter so much. One minute Peter was happily dancing along to some commercial on the tv and the next minute he was on his butt crying.

When Tony went to go pick him up but Peter screamed and tried to crawl away from Tony but Tony didn’t let him so he grabbed his foot and dragged Peter back towards him but that was a mistake because that only made Peter even more angry as he tried to kick Tony to let him go.

“No, daddy!”

Tony didn’t understand why his perfect child that was cuddling with him only minutes ago was now acting like the devil himself. “Peter, stop being so difficult”

That only caused Peter to scream and kick some more. He kicked Tony in the jaw causing him to drop Peter back onto the floor with a loud thump. Tony waited for Peter to start screaming even louder but when he looked down at him he was actually laughing at Tony.

Tony wanted to laugh with him but he was not about to tolerate this kind of behaviour from Peter. He wasn’t sure if it was teen Peter acting out in his toddler body but whatever is it, Tony hates it.

He picked Peter up by the underarms and carried him into the far corner in the living room. “You are going to sit here and think about what you did. No hitting, Peter”

Peter looked up at Tony with his big brown eyes that melted Tony’s heart every time he did that. Tony knew he couldn’t give in and had to be strong because he couldn’t have Peter going around kicking people and thinking it was okay.

“No! No daddy!” Peter tried to run away but Tony held him by the arm which was no match. Peter put up a fight anyways.

“Peter, stop” Tony said gently and placed Peter back on his butt in the corner. He wasn’t sure he should be giving a timeout to a two year old who is actually a fifteen year old but he’s gonna do it anyways.

“N-no! Daddy no!” Peter cried out again and Tony’s heart broke.

He wished he could scoop Peter up in his arms and hold him tightly but then that wouldn’t be teaching Peter a lesson and he needs to know not to behave how he is.

“No, Pete. You sit here until I say so…” Tony grabbed Peter’s chubby legs and pulled them until he was sitting in front of him “don’t move”

Tony then stood up and walked away as Peter burst out in tears. Tony ignored them no matter how badly he wanted to comfort his baby. He sat down on the couch even though his heart was breaking. He tried to ignore the cries of Peter but he found it really hard.

Tony decided to go onto his laptop and answer some emails until Peter stopped crying.

Pepper walked into the living room with a confused look on her face. “Tony? Why is Peter crying so much, it’s been over twenty minutes”

Tony glances up at her and stretched his arms out “Oh, yeah. He’s in timeout”

Pepper looked towards where the cries were coming from and saw Peter lying on the ground on his stomach while he kicked his legs. Her face softened at the sight but she knew Tony had a good reason to put Peter in timeout.

“Why’s he in timeout?” Pepper asked sadly as she sat next to Tony in the couch.

“He’s been crying a lot then he kicked me in the face and laughed” Tony explained. Saying it out loud made him feel pathetic but still, he needs to teach Peter that what he did is wrong.

Pepper laughed but then tried to stop herself. “So… he’s in timeout because he beat you up?”

“What?! No. He’s there because…” Tony eyed Pepper before crossing his arms and leaning back on the couch. “You know what? I don’t have to explain anything to you”

Pepper burst out laughing at the whole situation but decided to drop it anyways.

As they both sat on the couch together and did some work on their computers and phones, Peter still continued to cry in the background. Tony thought that at least by now he would have stopped but it actually seemed to be getting louder and it hurt Tony’s ears. A lot.

Peter on the other hand was having a complete temper tantrum and started taking off all his clothes the best he could. He got his pants off and his diaper off but once he tried to get his top off, it got stuff over his head and he started freaking out because he was stuck and he couldn’t see anything!

“Da-daddy! Daddy! Daddy!” Peter cried out he managed to stand up and run towards the couch but he hit something and it knocked him to the ground.

Tony heard the distressed cries coming from his kid and when he turned around he did not expect to see Peter on the floor lying half naked while he was stuck in his shirt.

The scene was actually quite funny if it wasn’t for Peter screaming and rolling on the ground. Tony stood up and walked over to Peter. “It’s okay. You’re okay, let me just…”

Tony stood Peter on his feet and helped him pull his shirt off so he wasn’t stuck in it anymore. He smiled when he could see Peter’s face but his smile soon left his face once he saw how sad and scared Peter looked. Tony hated seeing Peter look like that. Whether it was on his teenage face or his baby face, although to be fair there was only a small difference. Not much but still.

Tony lifted Peter into his arms and sat back on the couch where he held Peter in his lap and tried to calm down the upset toddler. “It’s okay, Petey. You’re okay. Daddy’s got you now”

As Tony rubbed Peter’s back he looked over at Pepper who was watching the scene with a sad yet happy look on her face.

Pepper watched Tony comfort Peter and couldn’t help but smile. She felt bad for the baby but watching Tony with Peter was… something else. It was amazing to actually witness Tony hold a baby in his arms and just feel the love just pouring off of him.

Pepper knew that Tony was going to be heartbroken when they figure out how to get Peter back into his teenage body. She saw how close Tony and Peter were when he was a teen but seeing the two together now that Peter is a baby, is something else. It almost breaks her heart that she’s going to have to witness Tony deal with his kid growing right in front of his eyes. Literally, if it works that way when they figure out how to get Peter back, if they can figure it out.

Tony bounces Peter in his lap and pulled the kids head away from his shoulder so he can look Peter in the eye. When he saw Peter’s face, he looked sad. His eyes were all red and he had dried tears on his face. Tony hated that he was the one who made Peter cry like this.

“I sowwy, Daddy!” Peter said through his tears. He grabbed onto Tony’s shirt and held on in a tight tiny fist.

Tony used one hand to support Peter’s back while the other hand he used to gently touch his face. “It’s okay, baby. You just can’t act like that, okay”

Peter nodded his head while he still gave Tony puppy dog eyes. “Kay daddy”

“Now let’s go put a diaper on you before you pee on me again” Tony went to stand up so he could put some protection on Peter before he had an accident which Tony did not want to clean up but then Pepper stopped him.

“Wait! I got an idea” Pepper said excitedly. Both males turned to look at her confused “I’ll be right back just… keep him naked”

Tony and Peter watched Pepper run off somewhere while they stood there confused. Tony had no idea what could possibly require Peter to be naked for unless it was a bubble bath but it was still too early for a bubble bath.

“Do you have any idea where she went?” Tony asked Peter as he lifted him up on his hip more.

Peter shook his head and laid his head on Tony’s shoulder which Tony loves whenever Peter does that.“I dunno, daddy”

“Hmm me neither” Tony waited for Pepper to walk back into the living room and when she did, she brought along a giant canvas and paints. Tony laughed because he could see where this was going and it’s not going to end well. For him.

“Pep, Pete’s not really capable of painting a picture for us right now. Unless you’re cleaning up the mess” Tony joked. He would clean up the mess either way because Peter is his kid.

“No, it’s not… he’s not gonna paint” When Pepper started making her way into the kitchen Tony followed her but he was now very confused.

“So you’re gonna paint and he’s gonna watch you without any clothes or a diaper on?” Tony joked. He was totally okay with Peter like this because Peter was happy but he isn’t so sure that Peter’s gonna be happy watching Pepper paint.

“No, we’re gonna paint his hands and his feet and put them on the canvas to remember how small he is forever” Pepper explained with a smile. Tony liked that idea but the thought made him sad. The thought that one day he might look back into this canvas when Peter’s a teen again and it’s gonna be really sad.

Tony knew he couldn’t be sad about that right now. There wasn’t even a grantee that they actually could get Peter back into his teen body.

“Alright, what do you say, Pete? Want to get painted?” Tony asked Peter who was already smiling just from looking at the paint. Tony stood Peter up on the kitchen counter while he still kept an arm around him just in case he fell off.

While Pepper was pouring out the pants to use, Tony was busy making Peter laugh but then Peter looked down between his legs and Tony knew what that meant but he was too slow because Peter started peeing.

The pee went down his legs and onto the counter top while Peter watched it like he was proud of what he just did.

“Oh, he’s peeing” Tony said. He wanted to wait until Peter was done now so he didn’t pick Peter up and have him pee everywhere.

“Move him to the sink” Pepper looked up and saw Peter peeing on the counter while laughing with Tony just watching him.

“I can’t! He’s a boy, Pep” Tony argued “if I pick him up and move him he’s gonna spray everything down”

Pepper rolled her eyes fondly and tried not to laugh too hard. Tony was right but it was still funny.

“All done!” Peter clapped his hands and then started trying to jump in his pee puddle on the kitchen counter. Tony lifted him up before he could continue doing that because that is disgusting.

“Nope. None of that” Tony held Peter around his chest as he used a wet napkin to quickly clean up just legs and his penis, he would give him a proper bath later.

After Tony was done cleaning up the pee on the kitchen counter, wow that was a weird thing to do. He placed his kid on the counter again. “Let’s do his feet first.”

Pepper grabbed the blue paint while Tony held Peter up. As Pepper painted his feet, Peter squirmed and giggled as Tony struggled to hold onto him. Tony loves that sound so much, he couldn’t help but try to remember how teenage Peter laughed but he couldn’t remember. He could barely remember what he sounded like. That thought scared Tony so much.

“All done! You can lift him up and hold him above the canvas while I place his feet down” Pepper explained. Tony held Peter by the armpits over the canvas while Pepper placed his feet down properly. Tony hopes that Peter does not pee right now. “Look how tiny his little toes are!”

Tony looked at the tiny feet on the canvas. He knew Peter has small feet right now but seeing them on a canvas just makes them look even tinier and it’s the cutest thing ever. Well, asides from his kids laugh.

Pepper cleaned Peter’s feet off the best she could but she didn’t get everything off because she knew Tony could do that for him in his bath later.

They then started painting Peter’s hands with a different colour of paint. The colour they used this time was a light green and when Pepper places his hands on the canvas, Tony almost started crying because his hands are so tiny and it’s adorable.

Peter kept trying to touch everything with his green painted hands so Pepper had to move quick before Peter touched something he wasn’t supposed to.

“I got an idea! We should paint your hand and place your handprint on the canvas then paint his hand a different colour and put it over your handprint so we can see the size difference” Pepper explained excitedly. Tony loves seeing her like this.

“It’s gonna be such a huge difference” Tony couldn’t wait to see how this was going to turn out. Pepper was going to paint his handprint blue and Peter’s yellow so you could see the contrast.

After they placed their hands down, Tony could not believe how crazy the size difference is. He knew Peter was so tiny but seeing it like this was crazy. Peter leaned over and painted to the handprints “daddy hand!”

“Yeah, baby. That’s my hand and your hand” Peter giggled as Pepper wiped both of their hands for them.

“Hold him up for a sec,” Pepper said with a smile on her face. Tony knew she was up to something but he held Peter up anyways “no, the other way”

“What?! He better not pee on me because my face is right in line with his peer” Tony said seriously. He could see that Pepper was painting his butt so Tony was excited to see how this was about to turn out but he was not excited if Peter decided to pee in this moment. Peter was kicking his legs out and trying to look behind him so Pepper had to hurry before Peter fell, like Tony would ever drop him.

“Finished. Look, Tony. Look at that tiny bum” Pepper cooed. Tony managed to get Peter turned around without touching his butt so Tony could see the paint on it. It was a dark blue painted bum that looked so cute.

Tony managed to place his butt print on the canvas with the help from Pepper. He lifted Peter up after he was done and looked at the completed canvas.

It couldn’t be anymore perfect than it was. Tony knew he would remember this day for a long time, whether they can find a way to turn Peter into a teenager again or not. Either way he would continue to work on it but looking at this canvas right now, Tony knew he would remember this day forever.

And he will definitely be hanging it in his bedroom.
