---------------------------------------

Hitoshi walked down the hallway letting out an audible groan as he stretched and yawned

He might physically not look like shit but man..

He was tired. He was always one to have trouble sleeping and insomnia like his adoptive father. Unlike him, Hitoshi did not take medication for it. It is mainly because they didn't know

Ever since they adopted Katsuki from his abusive mother all their attention was on him, he needed that support and love.

But now since they adopted Eri their eyes are on all the three kids meaning they were getting checked upon more frequently.

Hitoshi flopped himself onto his bed as he tucked a pillow under his chin.

He pulled out his phone and searched for the symptoms he had over the months.

'Age regression'

Reading the description of the "disease" he related it to Katsuki somehow, his eyes widened in disbelief.

This could not be happening.

' There must be a mistake' Hitoshi retyped his symptoms wording it differently but the same thing kept popping up.

Age regression

He gripped his hair in distress as his head became fuzzy, is this why he'd been waking up to soaked sheets? Or the high feeling he would get when he's stressed.

He didn't notice his bedroom door open "Hitoshi lunch is ready-" Yamada saw the distressed look on his son's face being the concerned father he walked over touching him knocking him out of his daze.

"What's going on?" Yamada asked once again with furry eyebrows he glanced over to his phone where he saw the words 'age regression' he might've been trying to help Katsuki out warmed his heart.

"It's nothing I'm fine, let's go" Hitoshi grabbed his phone before walking out of his bedroom with his father.

He walked into the kitchen to see his dad, Katsuki, and Eri sitting at the table preparing a salad.

He sat down quietly watching, Katsuki had seemed to be out of his headspace; he sighed in relief as that probably would've troubled him.

As everyone chatted and ate Hitoshi could feel Katsukis eyes burning into him "what the hell is wrong with you?" katsuki questioned Hitoshi had this gut feeling before sucking it down. " nothing I'm fine"

"Bullshit" Katsui spat

" boys, no fighting at the table" Shota spoke loud and stern.

Hitoshi huffed before picking at his food again, Shota and Yamada both sharing a look of concern.

Shota kept a note in mind to check on him later, although he is technically the middle child but older at the same time he was kinda distant from the family.

Once everyone was done with lunch Katsuki helped clean up the table while everyone ventured on their own.

Hitoshi stood up and walked towards the bathroom, the light was on as well the door was closed he sighed heavily as he knocked.

"I'm in here!" a high pitched voice yelled

"Right... Sorry" Hitoshi leaned against the wall as his bladder grew heavier the fuzzy feeling in his head isn't making it any better.

Eri began humming a happy tune as Hitoshi squeezed his legs. Tears pricked his eyes as he felt his pants begin to grow damp.

Eri heard sobs as she washed her hands delicately. She furred her eyebrows and opened the door to see her older brother on the floor.

"DADDY!!" Eri yelled for her adoptive father hearing fast footsteps in the hallway.

"Are you-" Shota started but stopped once she saw his sons in a puddle of liquid crying on the ground.

"Eri goes with Katsuki' Shota said before bending down to his son he began rubbing circles on his back to calm him down.

"What happened?" he asked with a soft tone trying to get a glimpse of his son's face.

His cries only got louder, he sighed as he tried to get the teen to stand up he's legs wobbled weakly before Shota brung him to the bathroom and ran a warm tub.

As Hitoshi's cries turned to sniffles but still silent tears shota began to strip his son and sat him inside the warm water getting a panicky gasp as he tried to get away.

"It's okay, it's okay" Shota calmed him down before massaging his head with his fingers to comfort him he saw how Hitoshi's eyes flutter low signaling he was tired.

Shota was confused, he was unable to stand and not verbal. Could he be regressing or is he stressed...Katsuki was never this young.

He texted his husband to come to the bathroom not wanting to yell because of Hitoshi.

Soon the door opened revealing Yamada with a confused look. "Is he okay..?"

Shota frowned shaking his head," He isn't verbal, and I'm afraid to leave him here by himself, could you wash him up while I prepare some clothes" his husband agreed.

–

Shota was in the teen's room looking for something comfortable to wear he didn't succeed and ended up going through Katsukis clothing he found some pajama pants as well as one of his shirts.

He hesitated on putting protection on the teen keeping in mind that he had an accident in the hall he chose to do so.

Shota returned to the bathroom to see Hitoshi wrapped in a towel, he had a red tint to his cheeks as he had his hands to his chest.

"Up you go" Aizawa grunted as he held the boy on his waist his husband standing beside him, Hitoshi scrambled uncomfortably as his father shushed and bounced him.

Reaching the shared couple's room he laid the purple-headed boy down on their bed, tears welled up in his eyes as he began to sob.

"it's gonna be okay hun.." Yamada smiled sadly as he rubbed the boy's stomach, not getting an answer.

"Could you go make him a bottle?" Shota requested of his husband, he left the room as soon as shota pulled out of bakugos pull-ups.

On shinsho had seen the pull up is cried and kicked viciously.

Shota groaned knowing the boy was probably uncomfortable, knowing he didn't regress voluntarily.

"Toshi I know this is new for you and you probably don't know what's going on but trust me it'll be okay.." Shota whispered sweet nothings into his ear.

He was able to get the boy dressed but his cries didn't stop.

–

Yamada grabbed a bottle from out of the cabinet rising it out before and putting milk in it throwing it into the microwave.

Bakugo was chilling in the kitchen while watching his pa. 'What is he doing' the blond thought.

"Where is your sister?" Yamada asked making conversation with his son.

"I put her down for a nap", Bakugo eyed his father suspiciously.

"That's my boy" he smiled proudly before taking the bottle and disappearing.

Yamada walked into the room to see Aizawa rocking a crying boy in his lap.

"Here" Yamada handed him the bottle,

"Shhh," shota slipped the bottle in too the boy's mouth as his eyes fluttered closed as he nursed from the bottle.

"Katsuki had never been this young before.." Yamada scratched his head.

"That's because he isn't Katsuki"
