Work Text:
Hobi and Jin felt like their life revolved around diapers, wet pants and changing sheets. They didn't mind – anything for their babies, obviously – it was just a lot of changing constantly. Stacked high in every room and cupboard in the house.
Yoongi was a calm baby. He was happy to snuggle up with whoever was available to coddle him, suck his thumb and relax. That's what regression was to him – a way to relax. Let go.
The first time he'd wet himself in little space he'd cried, and screamed, but hadn't pulled himself out of it, so really Hobi counted that as a win. They dressed him up in one of Kookie's diapers and spoke to him about it properly when he was big again. Yoongi agreed to diapers with red cheeks and a wiggle.
He settled into them soon thereafter. He would whine and cry every time he wet them, for a while, but eventually – when he got calmer, sleepier, a lot more ‘baby’, he really didn't react any more. He simply laid still as it happened, gurgling, waiting for someone to notice. Papa always noticed.
He wasn’t a big wetter as much as he was a frequent wetter, letting out little spurts often. It meant more changes than the bigger kids but little Yoonie didn’t really have the brain capacity to hold it for periods of time.
Yoongi hadn't reacted to a diaper for months – and then all of a sudden he was crying, pulling at it, and his caregivers were blindsided. He was so distressed their hearts were hurting but even after changing him into a different, dry diaper he was still crying.
Jin rubbed his tummy, listening to his baby wail, cradled against his chest. Yoongi didn't even want to nurse.
“Hey, Hoseok?” He asked after a minute, “Have you ever changed Yoongi’s diaper after a… bowel movement?”
Hobi shook his head as the baby's wails pitched, confused and overwhelmed.
“I think I know what's wrong.” Jin smiled, “You have to go poopy, hm?” He asked, “It's okay, sweetness. Do you need help?”
Yoongi shook his head but Jin laid him down anyway, cycling his legs and pressing his knees against his tummy. Jin had done this so many times with Koo it was second nature to him.
He tooted, and then it all came out, mushy against his behind and stinking up the room.
“There you go,” Jin shushed, "That's a good boy, Yoonie.”
His tears quieted, thumb in his mouth as he hiccuped softly.
“All those tears for just a little bit of poop, hm?” Jin teased gently, “You want me or Papa to clean you up?”
Yoongi was too out of it to care, but then Jiminie came bounding in, so Jin left to entertain him while Hobi changed their messy baby.
After that Yoongi really had no diaper objections. He would go wherever he was, regardless. He would sometimes whine but a kiss on the head would calm him down.
Never, ever, bring up diapers in front of big Yoongi, though. His lack of control while regressed had left him with less control while big and, well… Let’s just say a pack of the big boys pull ups had found their way into Yoongi’s closet, too.
Jungkook had never minded his diapers. He was their first baby, their little Koo, and when Jin had brought up his frequent accidents he had agreed to wear diapers almost immediately. The caregiver half thought that all the accidents were purposeful – as a way to get his diapers. Not that he would ever bring that up, of course.
Koo would run around in nothing but a diaper, if he was allowed, and enjoyed pointing out the padding under his pants. He was their little diaper baby for a reason and Daddy nor Papa would ever change that about him.
Koo didn’t have any tells when wetting his diapers – not even a satisfied noise, unlike baby Yoonie. He would usually go while playing, though, so his caregivers made sure to check him often. He was the opposite of his baby brother – holding and flooding his diaper, so it was imperative that they change him as soon as he wet, lest he develop a rash.
Jungkook had brought up the prospect of messing his diapers when he was still the youngest, the only baby – he was big, and very embarrassed, but the day before he’d dragged himself out of little space due to a bathroom emergency and it left him feeling all kinds of uncomfortable afterwards.
Jin, of course, had said yes immediately – he’d been concerned when his Koo aged up and rushed off, after all. Something as silly as a messy diaper shouldn’t ruin his day like that.
It wasn’t brought up again for months – Jiminie and Tae were little now, too, and Koo was playing with them when the urge hit him. He let his little boy instincts take over and scampered off behind their couch, squatting with a pink face. Jiminie said his face looked funny and left to go find Daddy, knowing exactly what his baby brother was doing.
Jin praised him when he crawled back out and took him to get changed, Koo having wet his diaper at some point too. He found himself crawling into small spaces to poop and, after a little teasing, his Daddy revealed that he found it very cute. His favourite spot will forever be behind the couch.
Jimin was, by far, their cheekiest baby. He was loud and proud, running around and excited all the time. He had wet the bed a few times before he was a regressor so it was no real shock when he ended up in night diapers. He announced his need for a change most mornings, climbing into the caregivers cramped bed and lying back, next to one of the babies, waiting for his turn.
Neither caregiver was stupid. They knew their Jiminie was a little brat and absolutely flooded his diaper intentionally every morning if he happened to wake dry. He was too giggly about it to not – he was the only baby to never cry over an accident, after all. His daytime pull ups were completely unnecessary in terms of potty training. He could use the bathroom absolutely fine if they weren’t home, god forbid he be caught with wet pants.
But still. At home he was delegated to padding because otherwise Jin and Hoseok would find themselves mopping up puddle after puddle. It was like a game to him, in a way. How long he could sit in a wet pull up until he was forced to change. If he could wet it until it leaked. If all five boys were little he usually could, just because of how busy his caregivers would get.
He’d only messed himself a handful of times. Always completely intentional, usually for attention. Standing in the doorway while Papa bathed baby Yoonie, or squatting in the middle of the room while Daddy tried to coax baby Koo out from behind the couch.
Jiminie was a brat of a baby, but he was their baby. Over the years of the boys regressing, Jin and Hobi had toyed with the idea of putting their little Min in diapers full time, but eventually realised that that would probably just encourage more accidents.
Taehyung had struggled with bed wetting into teenagerhood, and very occasionally into adulthood, so it really was no shock when he wet the bed regressed. He had cried about it initially but it didn’t take long for him to accept that it was not as big of a deal as he thought it was. He didn’t wet the bed every night, or even terribly regularly. Once a week at most, but usually less. He always wore pull ups to bed, just in case, and his parents were used to taking the same one off and reusing it the next night. Even rarer than his night time accidents were daytime ones, but he never seemed as upset about those ones. Perhaps because he was already so deep into his headspace.
Jimin helped him overcome his personal issues with wetting, too, and once he was comfortable with himself his little brother sunk his naughty little claws into him. Taetae was never one for being intentionally naughty without prompting and oh boy did Jiminie do a lot of prompting.
He convinced Taehyung that laying in bed and flooding his pull up was so much more relaxing than getting up and rushing to the potty. He didn’t do it every morning, because he didn’t enjoy the sensation of being wet like his brother seemed to, but it was definitely frequent enough for his parents to question him about it.
Jimin had never managed to convince him to wet his pants purposefully, probably because wet jeans were so much worse than soggy padding. But he had convinced him, no more than twice, to mess his pull up in the morning. Jin was sure the first time was mostly an accident, probably just Jimin noticing his brother in distress and telling him it was fine to use his pull up. The second time? That was intentional. Still, Jin didn’t mention it, just asked if he wanted a pull up during the day, too.
He received an embarrassed shake of the head and it didn’t happen again.
Joonie is a big boy. He doesn’t wear diapers or pull ups; he is a very good, very big boy. He wears his big brother and good helper titles with honour. He even helps change the baby's diapers sometimes! Koo loves it when Joonie helps.
So when Joonie, big boy extraordinaire, does have accidents, it’s a whole ordeal. Sobbing doesn’t cover it.
His very first accident, about a month after he’d started regressing, had happened when he was big. He had gone to bed big and woke up big – big and wet. He shifted in his bed and, initially, thought one of the boys had hopped in with him and wet the bed, then woken up and ran off to hide. All three of his dongsaengs, Yoongi not yet a little, had wet the bed while big. And all three of them had been little yesterday. It would make sense. Namjoon decided he would simply strip his bed and let them come to him about it.
Then he pulled back his covers.
His world stopped. His sweats were soaked – crotch, inner thigh, right down to his knee. His eyes widened dramatically and then he was dropping, hard and fast, cries bubbling in his throat as he sat in his cold puddle, so completely overwhelmed. Jungkook burst in, clearly not little, and that somehow made Joonie cry even harder.
“Oh, Joonie, it’s okay,” He soothed, walking over to the bed, “Daddy is coming, yeah? He’s just getting out of the shower.”
As Jungkook approached him Joonie curled in on himself, not wanting his mess to be seen. If he was thinking clearer he may have pulled his blanket back over himself to save his dignity.
Jin burst in a few seconds later, hair dripping and half dressed, but Joon couldn't find it in him to feel bad. His wails picked up the second he saw his Daddy, wiping his tears on the back of his hand as Jungkook left, leaving Joonie with their caregiver.
“It’s okay,” Jin had soothed, immediately aware of the issue, “It’s just an accident, Moni. Why are you so upset, hm? We can just get cleaned up, okay?”
It had taken over an hour – a long, tear filled hour – but eventually Joonie had calmed down and was clean, the mess being washed away. He was the only little in the dorm, Koo having left a few minutes prior to meet Taehyung – Yoongi was in the studio, Jimin and Hobi working on new choreo. Daddy spooned cereal into his mouth and then he felt okay.
Not every accident was as distressing as that one, with the exception of his one daytime accident, but every time he woke up wet he cried, hard, and waited for Daddy or Papa to come fix it. They always did. They kept a pack of pull ups in his closet although he’d never opened it. But it sat here, under a blanket, just in case.
