Before they would just call it his "shut down" time. Where he would curl up next to his best friend (preferably in his comfy bed with him, but the common room couches work too, or his mother's couch) and put headphones on and not say a word. He would put on a playlist of acoustic covers, a few video game soundtracks (mainly Minecraft and Animal Crossing), and instrumentals. A playlist of soft music helps to clear his mind and make him feel fuzzy.

He and Kacchan don't speak. Heck, sometimes the blond does nothing to recognize the other's presence besides moving his arm to the back of the pillows or couch so Izuku can tuck himself right up next to his warm body.

They communicate through texts during this time. Most of the time Izuku is already on his phone (scrolling hero blogs, social media platforms, or just cute pictures he has saved on his Pinterest boards) and so Kacchan (who is probably on his own phone as well) will just text Izuku his questions so that he doesn't have to stop listening to his music or anything.

And his questions are never too heavy or serious. Always just:

you okay?

do you need anything? water? snacks?

you mind if I turn something on the TV?

They sit like that for hours or more, always calm and always peaceful. It is nice for Kacchan as well, getting to take care of his best friend and keep them both safe. It felt like winning to him.

Izuku doesn't even realize he's regressing until much later; he finds out about regression and his whole world unlocks.

He goes to Kacchan about this and the blond just says, "wait you didn't know that was what was happening?"

From there they develop a mutually established caregiver/little relationship. Izuku gets some of his first little gear (a chew necklace and an All Might-themed stuffie) and his mind eases into it perfectly.

Their large, third-year bodies sinking in her cushions and falling off the poor piece of furniture, and their heads lulled together in sleep, nearly breathing the same air.

It is finally over, she sighs to herself with a fond smile. The bullying that her son lied to her about, the rivalry, the hatred, the tears— it is all finally over.

Seeing them together like this, a mirror image of how they used to be as kids (the two of them were very sleepy children and loved to cuddle each other), gave her an overwhelming sense of joy.

Her heart is full because her boys are friends again.

It's been years and they are finally back. And yes, they are her boys. Just like the two of them are Mitsuki Bakugo's boys as well. They were together so much as kids that the two mothers practically raised them together.

And if Inko, once her tears have stopped streaming, goes and calls the other mother, a woman she talked to less and less as their sons worked out their differences but whose contact she never lost, to retell how she found the two of them. Mitsuki demands a picture and so Inko sneaks back down to the living room again.

A little while later, when the two wake up (blushing hard when they realized that they had once again gravitated toward each other in their sleep), Inko pretends nothing is wrong and they are both grateful.

They also don't acknowledge how it is the best sleep they have gotten in a little while, even if their necks are a little sore from the awkward angle of the couch.

And two weeks later, when Mitsuki calls up to Katsuki that dinner is ready and both her boys come down the stairs, it isn't an unpleasant surprise to the Bakugo parents. They just set aside another plate and strike up a conversation with Izuku as they do their own son.

Oh you are absolutely right!

When the others come out to him about their regression they fear that he might judge them on it and he can sense that; so he takes the time to make them their favorite snackies and put on their favorite shows. He takes the time away from his own training to care for them.

It is the only time that he is ever really physically affectionate. He runs his hands through their hair and praises them on their coloring pages, games, puzzles, etc. that they've done. It is a caring side of Bakugo that no one was expecting but everyone loves to see.

It is really sweet but when they are big again and ask why, he clams up. He can't come out and say it is because he craves that kind of attention when he is regressed, that his little-self is crying for some nice head pats or for someone to pour some juice into his favorite sippy.

He keeps that part of himself locked away, convinced that they will all see him differently once they know despite nothing changing for the person he is caring for. It is just different when it is himself, or so he thinks.

// Thank you for this ask, anon! This turned out a little angstier than I meant it, so I will tag it as such. But what do you think? Do you think Bakugo can hide it forever or is someone going to find out? I am curious to know what you guys think, so leave a comment/reblog/ or just tap an answer on the poll! I love interacting with people <3

little!katsuki who calls Izuku "dada 'Zuku" or sometimes just "dada"

the first time katsuki regressed in the common room (they had previously discussed it, so everything is consensual), he keeps his face buried in Izuku's chest or shoulder and just keeps mumbling "dada, dada Zuku, dada," over and over.

Izuku eventually gives him his favorite rubber chewy toy meant for teething (it is the shape of a lego) and that turns his babling into indecipherable murmurs.

Izuku watches some of their classmates (Uraraka, Momo, Kirishima) coo silently at the usually fiery blond cuddled on the couch next to him. Izuku knows how special he is to get to see this as often as he does, how close the two of then are nowadays.

katsuki spits the lego piece out and it falls onto his chest with a "plunk!" sound, then red eyes meet green. "dada, hungies," is mumbled past his lips.

She hears about it through Denki and Sero, who are very involved with the topic. Sero is Denki's (and Shouto's, but no one else besides Sero really knows that) caregiver.

They play video games together and do finger painting sometimes. It is really fun and is a nice way for the both of them to relax after the stresses of UA's hero course.

Denki decides that he wants to include more people with his regression and be able to go into littlespace where ever in the dorms he feels like. So, they start talking to people about it.

Some get it and some don't. Momo falls in the latter category.

"Why can't you play those games without Dino pajamas and a sippy cup?" she asks genuinely.

Denki just shrugs, grin never falling from his lips, "it's just easier to slip and have a good time overall. to not have to worry about every little stress and only focus on.. well, little things."

She nods, but it is clear to both boys that she doesn't understand.

She declines their invitation to see a play date in action, but not because she isn't curious to learn more but because she must do some research first. She hates when she doesn't know something.

Research is what takes up the rest of her evening time and so it is a few days later before she can find Denki alone to ask him more about it. She asks and he answers.

She doesn't ask to be around him while he's little for a little while still, but when she does she brings supplies. She waited until she was completely comfortable with it because she read that having an unsure atmosphere can sometimes throw a little off. So she brings stuff.

They play with Play-Doh together and make multi-colored sandwiches that she had to stop him from eating more than once. Sero says he's about four years old.

"Tanksies, Momm...oh," he says after the materials are all put away and he is laying his head on her shoulder.

The name sounded weird from his garbled speech. As if the last syllable was a mere after thought than intentional.

"What did you just call me?" she asks gently, nudging his head up so that she can meet his eyes.

He pops his thumb in his mouth and stares back at her.

Sero moves over from the other side of the room (he'd been there the whole time to keep a watchful eye on his little guy for Momo's first time with him). He sits on the other side of Denki and gently pulls the boy's thumb from his mouth.

Denki makes an argumentative sound, but Sero is there to hold his hand a shush him. Momo watches this play out while quietly observing.

"Shh, you know you can't suck on your thumb anymore. Not after you hurt yourself..."

Sero's voice takes on a tone that Momo has never heard before when he talks to Denki while he is little; more of a parental talk than she would have ever given him credit for before this moment.

Sero guides Denki to sit closer to him while he relaxes into his new spot on this couch. Denki sucks his thumb when he is anxious, so Sero had told Momo that the best thing to do is hold his hand and cuddle him.

It doesn't work this time.

"Nhnoo," Denki fights back, drawing out the consonant sounds.

"What, why not? You love cuddles," Sero watches Denki with a certain level of exasperated fondness in his eyes.

Honestly, Momo hadn't realized they were this close.

Denki shakes his head and says, "wanna still sit next to Mama." He cuddles back into Momo's side.

Sero's eyebrows shoot up to his forehead and he let's Denki snuggle close to the woman there.

Momo is speechless.

Mama?

Had he meant to say her name? Or was it intentional? She didn't know.

So she asked: "am I Mama, Denks?"

Denki's grin is immediately as he rubs his cheek into her arm and shoulder. "mhmm, yesh... Mama, mama, mama..." he murmurs, voice growing heavier with incoming sleep.

Momo maybe finally understands.

Being called that name makes her feel special. Like, his simple mind chose her to look after him. She was deemed special enough by someone in such a vulnerable position to be called that?

Sero grins at her while watching this all play out on her face while Denki snoozes against her.

Later, once Denki is big again, they ask her if the name is okay and if she'd like to be more involved in the future and she agrees immediately.

dinosaur drawings

green crayons, markers, pencils, etc

plants (especially leaves which he will tug off of trees and stare at it or give it to his Zuzu!)

green stop lights (if he sees one walking down the street he'll point it out to anyone who will listen and then pout when it turns yellow and red)

there was one time where Izuku had brought a house plant from his mother's house and he hadn't realized just how little Kacchan had been until he had to rush from his bathroom to stop the boy from popping a vibrant leaf into his mouth. luckily he was just in time

Of course, he'd been a little pouty about it at first — Kacchan always has a lot of emotions when regressed and he doesnt always know how to express them, so pouting is his default — but then Izuku explained to him that leaves could potentially hurt him if he ate them. Kacchan understood.

And then, cue his panic the next time he regresses and Izuku tries to eat a salad around him.

Little Bakugo is so obsessed with Animal Crossing. He doesn't ever touch the game when he isn't regressed, but once his mind slows down and he relaxes into that state of mind, all he wants to do is play his game!

It makes the job of being his caregiver very easy. It is often Izuku that fills that role, and really, all he needs to do is make sure that his Kacchan is nice and comfy on his bed and has his Switch with him.

Izuku also has a Switch, and sometimes Kacchan will whine and beg him to play and they will go collect all the fruit on both of their islands together! Izuku secretly keeps planting more and more fruit trees on his island because he knows how much the blond loves doing that. So the more trees, the longer it takes to gather all of the fruit. 

It is just something that the two of them do together to pass the time. Kacchan really enjoys the game, and nothing can stop a tantrum in its tracks faster than placing the boy's gaming device in his hands with the game's loading screen up.

In fact, there had been one time when Izuku had been off campus busy with his work-study and couldn't be there for Kacchan when he wanted to regress. So he went to some of his other caregivers, Kirishima and Sero, to keep an eye on him while he was little. They didn't know the little trick to calm him down.

So when they told him that, no 'Suki, we can't color with you right now we have homework to do, and the tantrum of the century started, the two boys had to just suffer until the green-haired boy got there.

One quick text at the time of Izuku's usual arrival had said boy knocking on Kirishima’s door promptly. He was there for all of two seconds before he went over to Kacchan and picked him up to settle him on his hip — the small-minded boy knowing to wrap his arms and legs around him immediately.

"You wanna play our game, honey?" Izuku coos, easily carrying the blond with one arm and wiping his tears away with the other.

The other two in the room stared back with slack jaws. One, Katsuki never let anyone else pick them up, and two, the way his crying stopped and his face lit up so quickly at the mention of whatever their game is.

"Yes, pwease!" Kacchan grinned, tugging excitedly on Izuku's shirt. "Can we 'Zuzu?"

"Of course, kiddo! I wouldn't have asked if I didn't want to," he answers easily. "Say goodbye to Kiri and Sero first though," Izuku's tone has turned a little stern and he tilts the little towards the two still staring at them.

Kacchan, reminded of the ill feelings he'd felt during his tantrum, buries his face in Izuku's neck and mumbles his goodbyes.

"Nu-uh," Izuku says gently, bouncing the boy on his hip to get him to stop hiding. "Proper goodbyes now."

"Literally how?" Sero asks in disbelief at the same time Kirishima says, "he listens so well to you."

Izuku sends them sympathetic smiles paired with a one-armed shrug (the other arm still occupied with holding Kacchan).

But then a hand unfurls from Izuku's shirt and waves at the other two boys, and then a second later Kacchan was picking his face up to look at both of them. "Goodbyeees... sowry for cryin, I really wan-ned my game..."

Kirishima and Sero nod and smile at him, still having no idea what game they're talking about. They tell him that crying is okay and that sometimes it is difficult to express your emotions while Kacchan just hides in Izuku's neck again.

Izuku, sensing their confusion, promises himself to text their caregiver group chat to explain what Kacchan is talking about once they get back to his room. He nods to both of them and leaves the room then, carrying the little over to the elevator.

Even though Kacchan's bedroom is right next door, Izuku knows both of their Switches are up in his room and he knows little Kacchan likes his place more.

"How are you doing, buddy?" Izuku asks while he switches what hip Kacchan is sitting on.

The elevator dings and the doors open to reveal Todoroki and Iida. The two step to the side to politely give the pair more room. Izuku smiles his thanks to them and steps on.

Kacchan hides more in his neck and Izuku can't help but bring his hand up to tickle at his chin, "hmm, Kacchan?" he prompts.

"I okay now that you got me's," he says honestly, mumbling it into Izuku’s shoulder.

"Awe," they both hear Iida coo softly.

Izuku grins, turning to him, "he is adorable isn't he?"

The three of them all agree and Izuku laughs lovingly at the soft embarrassed whines they all hear.

Their stop comes first and Izuku tells the other two his goodbyes before stepping past the doors. They make it to his dorm without issue after that and he gets Kacchan all tucked into his bed, kissing the blond on his forehead sweetly before stepping away to grab their gaming systems.

"I'm sure we have more fruit to pick if you wanna play together today?" Izuku asks as he plucks one Switch from the dock connected to his TV and the other from its spot on his desk.

When he turns around to hand the blond his device, he sees Kacchan spacing out staring at his own hands. Izuku coming into his line of sight doesn't change a thing.

Izuku understands immediately; it is one of Kacchan's tells when he is coming out of littlespace. He waits patiently for a couple more moments before he calls out the other's name softly, "Kacchan?"

"I'm okay," he says, voice cracking as he talks in his lower register once more.

Izuku smiles, "welcome back, how are you feeling?"

He only blinks for a second more before making eye contact with Izuku for a mere second before looking away. "I'm good, th-thank you for.. that..."

When Kacchan is big, he sometimes has a hard time showing his gratefulness. Izuku still appreciates any attempt he can get. He also knows there are some other questions he has still.

"You wanna come up fully or go back under?" Izuku is careful to keep his tone neutral and caring. He really doesn't mind either option for his friend, knowing that he'll be here for him either way.

Kacchan shrugs and waits a moment, thinking and staring at the Switch in his hands, before flicking his eyes back up to Izuku to gather his reaction. "Go back if you're okay with it?"

Izuku stretches his mouth in a big, proud grin. He comes over to sit on the bed next to him and gives him another forehead kiss (they are secretly Kacchan's favorite). "Of course, little one, you let me know when you are ready to play and I will get my game loaded up. For now, I am going to put away my books, okay?"

He waits until he has Kacchan's nod in agreement before getting up from the bed and dropping the backpack he had brought in with them. He knows that transitioning from his regular head to his little one can be a bit difficult for Kacchan sometimes, so he turns away to give the boy some privacy while he really does busy himself with putting his textbooks away in his desk drawers. They've been doing this for long enough that Izuku knows Kacchan's needs.

It isn't long before he hears, "otay, 'Zuzu! wanna go your island firsts."

Izuku smiles and happily grabs his own gaming console. He loves how simple-minded his little Kacchan can be sometimes.

This is all a matter of opinion, as to who I think is a little and who I think would be their caregiver/babysitter. Some characters are both/flips! These are also little stories of how they learned about regression or found out about their classmates, etc. These are just bare minimum scenes and little headcanons. If someone would like a full fic of it, feel free to prompt me! My ask box is always open. *.·:·.✧ Masterlist of Characters ✧.·:·.*

Katsuki

Katsuki has almost always known he's a regressor.

And with the general exception of Izuku and Denki, he doesn't do very well taking care of another little. It is just something about those two that have his caring instincts spiking, but pretty much with everyone else he is awkward around, so he tends to not participate in their care.

Katsuki has known that he's been a regressor since he was a pre-teen. It started at the beginning of middle school when he started having frequent nightmares and needed the comfort that he knew his parents would never be able to give him. He needed to find ways to comfort himself.
