Peeta as the smallest of 3 brothers definitely had to resort to dirty plays like biting in his youth.
First off, you're right and you should say it. Second off, Peeta being the youngest is 1000% a dynamic in his relationship with Katniss once they start to recover.
No bc listen. I was the youngest of three siblings and while we never got into physical fights I learned QUICK how to use my mouth to win what battles couldn't be fought physically because my siblings would 100% go to jail for trying to rock a 3 y/os shit. So Peeta was running his mouth religiously around the household. Can't tell me otherwise. "If it weren't for the baby??" Girl, he was biting AND flappin his lips. 100% would get pinned to the ground by his brothers and be like "wow I feel bad for your girlfriend" before getting his shit rocked. He'll offer them tips inbetween punches. "Aim for the throat. Wow, you're still pathetic."
Second, Katniss is the eldest, Peeta is the youngest in their families. Once they're more secure in their relationship, Peeta is 100% causing fun! problems 24/7. She's stressed the fuck out she's gonna come home one day from hunting again and half the house is repainted with all of the furniture just shoved into one big pile away from the drying walls like "WHY DID YOU DO THIS??" "bored :))" because he's so dangerously intelligent, I'm thoroughly convinced he's a practical fucking moron. He probably had to create his own entertainment as a child, he's used to being ignored. If he gets an idea to rearrange the furniture, he just does it. Katniss and Haymitch both have to intervene with how much this happens because Katniss complained about it to Effie once, and Effie started rambling about this thing called "feng-shui," and now Peeta is completely obsessed and will spend several hours to the point of obsession planning with Effie not just his decor, but literally fucking everyones, and Katniss tried to warn Haymitch "Hey, we need to fucking stop this," and Haymitch just said "get out of my house." But now Haymitch is too sober to deal with the constantly changing furniture, and why is this idiot painting his ceiling, and can you please pick up a hobby that doesn't involve majorly changing the layout of our houses? Peeta says no. Katniss instead comes home to Peeta having several geese chasing him at Haymitchs training. He's been waiting for an excuse to reveal this.
She stops feeling bad for needing his constant comfort once he starts biting her out of boredom. Oh, come on. You can see it. He would absolutely look at her arm one night and go "you look nice :))" before taking a giant fucking bite that makes her question every decision she made from age 16-18. There's a solid minute where they just sit in their bed at a standstill. She's holding her book in shock, he's just frozen still biting her. She says "What the fuck" he says "nostalgia :))" to which she's further confused and slightly terrified. She learns how to duck. He learns how to lure her in easier. Post-canon angst + comfort is cute, give me chaotic Peeta torturing his wife who just wants five minutes of peace but secretly adores her dangerously clever idiot of a husband
Imagine when they have kids. That woman is gonna go from "peetas baby!" To "your child."
He likes tossing the motherfuckers in the air. He's the kinda dad who will take off RUNNING with the shopping cart, shove the thing as far away as he can and just wave "bye bye! :))" to the baby inside of the cart that's laughing wildly while Katniss is just chasing this fucking thing down through the store like it's the quarter quell all over again and everyone else is just watching like "Jesus Christ he's doing it again." It gets worse when Peeta collaborates his children with the attacking geese to use against Haymitch when he tries to prevent him from repainting his ceiling again.
I've said this before but when everlark has kids, Katniss is shocked every time they fight whereas Peeta scruffs them apart like two angry kittens. Because obviously Katniss wasn't six brawling with two year old Prim, but Peeta and his brothers I think were a lot closer in age. And also their household used violence to fix problems (learning by example). So siblings beating the crap out of each other is normal + expected for him.
No bc Katniss would be borderline freaking out like "no!! Why are you fighting!!" And Peeta is just unfurling the emergency get along shirt like he's been fully prepared since the day he found out they successfully conceived #2. Katniss was 100% expecting a loving, tender bond like she had with Prim and Peeta is just listening to her while actively dragging their children by their leashes like "mmhm, yes dear"
I feel like they'd be legit the sweetest children ever too but in the most evil way. Like they 100% know if they just look at their mother the same way their dad does with the puppy eyes they're going to be fat with cake by noon and Peeta is just gripping Katniss by the shoulders shaking her like "NO you CANNOT listen to them, do NOT make eye contact they KNOW your weaknesses" while their kids are behind him with big eyes like "we hunger mother :((" and Katniss 'I cave to the whims of my loves' Everdeen promises Peeta she will not feed the creatures only to shove a full box of cookies in their arms and shoo them away the minute he leaves the room. So when the kids eventually fight over who gets how many Peeta is just sadly holding up his children scolding himself for not assuming this would happen while Katniss is just distraught for technically causing her babies fight and breaking her promise to Peeta. This is made worse by the geese (can you tell I admire the geese)
