Hitoshi groaned at the sound of his alarm blaring, a tired hand reaching out from under his nest of blankets to shut it off. He rubbed at his eyes and groaned again, feeling halfway to the grave as he forced his body up into a seated position. A wave of dizziness hit him hard, the third entirely sleepless night in a row catching up with him, and Hitoshi squeezed his eyes for a long second, willing it to go away. At that moment, the main reason for his problems reared its ugly head, the pain making him double over with his arms wrapped tightly around his torso. His bowels were cramping so horribly that he was sweating and the teen ached for release. He was fine though. At least he told himself that. He didn't need any help.
It was hardly the first time that he had faced this problem, but it had never been this bad before. Hitoshi knew it was because of his status as a Little. Littles usually got upset and they had a hard time doing everyday things when they hadn't regressed in a while. While Littles who regressed to the ages of 3 and up could usually regulate their bathroom needs with varying degrees of success, Littles who were in the infant to toddler range couldn't. They needed at least a part of their diet to be liquid to help get things moving. They usually got a bottle with a mix of nutrients and fiber, which encouraged their bodies to have bowel movements. Hitoshi, who had never had a caregiver, had also never really gotten bottle fed before. His foster parents usually just saw him being Little as a burden and the teen had learned to hide his status well.
Hitoshi groaned again as another flare of pain ripped through him, this cramp more urgent than the last. He just wanted to go already, but no matter how hard he strained, or how long he spent on the toilet, he just couldn't go. Hitoshi pushed himself off the bed and made it about two steps before collapsing to the floor in pain. He dropped into a squat, hoping to relieve some of the pressure, tears prickling at his eyes. He grunted and strained hard, trying desperately to have a poop, not caring if he made a mess of his pants. He just wanted the pain to go away at this point. His crotch suddenly grew wet, spurts of pee spattering onto the floor, and Hitoshi let out a sob, frustrated and embarrassed beyond belief. It takes awhile for the stream to stop,and when its finally over, his bare feet are shifting around in a puddle of his own urine, and his pajama pants are soaking wet and clinging uncomfortably to his skin.
Hitoshi continues to sob, biting his lip to muffle his distress. He resists the urge to grab his phone from the nightstand and call his daddy mentor. His little side wanted desperately to be held by the familiar, comforting presence right now. Wanted to let Aizawa take care of him and take away the pain. But, he couldn't. He shouldn't. Aizawa had better things to do than take care of him. Another few painful contractions hit him in rapid succession, leaving Hitoshi breathless and sobbing even harder. Before he could think twice about it, he was already crawling to grab his phone, blinking through blurry eyes at his contact list. There was only his social worker, his foster parents, Midoriya, and Aizawa on there, so the man's number was easy to find. He pressed the call button and with shaking hands, put the phone up to his ear.
"Shinsou." He picked up after two rings, and the tired voice crackled to life over the speaker.
Hitoshi just sobbed harder at the sound.
"Hitoshi?" Aizawa's voice got softer, a worried edge seeping into his tone. "Kid, are you okay?" He drops his voice to a whisper. "Are you feeling little?"
"Da-ah" Hitoshi sputters into the speaker, no longer able to make coherent words as he slipped further into littlespace. "Dada!"
"I'll be there as soon as I can, just hang tight baby."

Shouta sent Hizashi a quick text asking him to take over his class, grabbed his diaper bag, and practically ran to Hitoshi's dorm room, ignoring the confused looks that he got from his students. He swiped the teacher access card on the door, bypassing the code and swung the door open. What he found inside broke his heart.
"Oh, kiddo." He crooned softly, using the voice that he specifically relegated to Littles. "What happened?" He clicked the door shit behind him before carefully approaching his trainee.
Hitoshi was on the floor, on all fours, pale and sweating with wet pants, a big puddle underneath him, and massive bags under his eyes. The poor kid sobbed louder at his presence, reaching out for the older man. Shouta obliged his request, pulling the boy in to lean against his chest. "Are you tired buddy? Is that it? Is that why you're so upset?" Shouta gently asked, rubbing the teen's back in a steady rhythm.
"Dada!" Hitoshi cried, followed by a string of incoherent babbling.
"Oh, you're really little, aren't you? You're just a baby." Shouta softly remarks, more to himself than the kid in his arms.
Hitoshi groaned in discomfort and sobbed harder, hands clutching tightly at the fabric of Shouta's hero suit.
"Is that what has you so upset sweetie? You got really little and got scared?"
"Dada!" Hitoshi wailed again.
"Dada's here, baby. I'm here." His heart soared with joy at his trainee, who he already secretly thought of as his son, thinking of him as his father.
The teen suddenly shifted in his arms, his legs pulling up into a low squat that Shouta was all too familiar with. Shouta just continued to rub his back while he strained to go, praying that he had enough wipes for he knew what was coming. Hitoshi whined and whimpered, trembling in his hold and sobbing harder when he failed to release. "It's okay buddy, don't hold back, just go."
"Dada!"
"I know, I know it hurts sweetie, but you're gonna feel much better, okay?"
"Dada, can't!"
Shouta scooped him off the floor and into his arms, not caring about the urine soaked legs wrapping around his waist. "Alright, lets get to Recovery Girl. She's gonna give you something to make you feel better, okay?" Hitoshi looked at him through lashes sodden with tears and Shouta pressed a kiss to his sweaty forehead, walking back out of the dorm room and off to Chiyo's office.
"What's wrong?" Chiyo answered quickly after he knocked on the door, her eyes sympathetic as they regarded the upset little in his arms.
"He can't make a bowel movement."
Chiyo nodded, waving her hand. "Come with me." She said, disappearing back into the medical bay.
Shouta hurriedly followed her, gently shushing Hitoshi when he let out another pitiful wail of pain. "I know; you're gonna feel better soon kid."
Chiyo opened the curtains to an empty bed, her wizened finger tapping the edge of it. "Put him up here. I have to go find the medicine. Shouldn't take long." She said, scuttling off again to search the many cabinets of the medical bay.
"Okay, baby." Shouta crooned as he set Hitoshi down, carefully detaching himself from the clingy little. "Lets get you changed." The lilac haired boy loudly whined in protest, more tear welling up in his eyes as he weakly made grabby hands at Shouta. "I know buddy, but I have to change your bum. I'll be quick, okay?"
Hitoshi reluctantly nodded after a second, letting Shouta pull his pants down and off, whimpering when his wet skin was exposed to the cool air. The ravenette took the diaper bag off of his shoulder and set it down on the bed, digging through it quickly before pulling out a diaper and wipes. Hitoshi shivered and whined again when the cold wipes touched his genitals, but was quickly soothed by Shouta's gentle shushing and a calloused hand being placed lightly on his stomach.
"There you go, almost done kid." Shouta said as he lifted his legs and wiped the urine from his bum. "And you're done." He announced soon after, unfolding the diaper and placing Hitoshi back down on it. He didn't bother doing up the tapes, knowing that he would just have to undo them again in a few seconds.
"Found them." Chiyo said, shuffling back into the room, the medicine bottle in her grip loudly shaking around. "Here," she continued, opening the bottle and dropping two large white pills into her hand, "do you want me to do it, or?"
Shouta turns his gaze back to the boy squirming in discomfort. "Hitoshi, we found some medicine that will help you feel better, but you're going to need some help with it. Do you want me to help you take your medicine?"
Hitoshi quickly nods, arms reaching up to try to grab at Shouta again. "Dada."
"Okay baby, Dada's going to get you feeling better soon." Out of the corner of his eye, Shouta sees Chiyo trying to hide an amused smile behind her hand. The man ignored her and snapped on the gloves that the older woman offered him, pushing Hitoshi's legs legs back up to his chest. "Deep breath kiddo, and just try to relax. It's gonna be uncomfortable, but try to stay still for me okay?" Hitoshi whined as the first pill was pushed into his bumhole, squirming to try to get away from the sensation. "I know, I know it's not fun, is it sweetheart?" Shouta inserted the second pill soon after the first, prompting more distressed whimpers from Hitoshi. The ravenette shushed him, gently rubbing his stomach in an attempt to calm him. "You're almost done, you're almost done." Shouta waited until the pills had started dissolving to remove his finger. "Good boy Toshi." He praised, expert hands doing up the tapes of the diaper.
Shouta pulled Hitoshi back up into his arms when he was done, pacing while shushing and bouncing him as they waited for the laxatives to kick in. While they waited, the man swiftly pulled out his phone and sent a quick text off to Nedzu, asking for a janitor to be sent to Hitoshi's room. Shouta registered Chiyo bagging up Hitoshi's pants and throwing them out, murmuring to her a quick thank you.
Ten minutes later, the little's squirming increased, his groans and grunts becoming more frequent as the need to go grew stronger. Shouta just rocked him and whispered encouragements in his ear, shushing his cries.
"Dada, need go!" Hitoshi wailed in discomfort.
"I know you do. Just go baby, I'll change you after."
"Poopy." The boy whimpered, lifting up his bum.
Shouta hunmed in agreement. "Are you going to be a good boy and make poopy for Dada?"
Hitoshi's eyes lit up a little at that and he nodded, clutching onto Shouta tighter as he finally released his bowels. The room filled with the putrid scent of feces as the boy's diaper filled up and the erasure hero had to suppress the urge to gag at the stench. Hitoshi relaxed as more poop landed in the padding, practically boneless when he proudly announced, "All done."
"Good boy, good job Toshi." Shouta praised as he laid the little back down for a change. Hitoshi whined at the loss of contact, but was otherwise compliant as the older man opened his diaper up. "Whoa." Shouta exclaimed upon seeing the mess. "You really had to go, huh kid?"
Hitoshi just babbled, sticking his fingers into his mouth. The ravenette grabbed a pacifier from the diaper bag and replaced his fingers with it, and the boy happily sucked on that instead.
It took a while for Shouta to wipe all of the mess off of his skin, but luckily Hitoshi seemed pretty good about diaper changes. He just babbled mostly, squirming occasionally, but not making too much of a fuss. Shouta quickly finished taping him into a new diaper and threw the old one in the trash, along with the used wipes.
Just then, Chiyo popped her head in again. "All done?"
"Yep, all better, thank you."
She waved his gratitude off. "No need to thank me. I just got off the phone with Nedzu, Shinsou will be on littlespace leave from school for the next couple days, so we'll have to find him a caregiver, unless...?" Chiyo sent him a knowing look.
"I can take care of him if someone can take over my classes."
"I'm sure we can figure something out. Now go." She said, making a shooing motion with her hand. "Looks like someone needs a bottle and a nap."
Shouta nodded, pressing another kiss to Hitoshi's forehead, and left. The little shivered as they walked the halls, too cold in only a diaper and a t-shirt. Shouta maneuvered his capture scarf to wrap around him and Hitoshi reached out to run his fingers along the material. Now that he was no longer in pain, it was becoming evident that the lilac haired teen was a very curious little. He looked around the halls with wide eyes, his hand sometimes poking out to point at whatever caught his eye.
"Yeah baby boy? Were you good today? Were you a good boy?" Shouta softly crooned to him, leaning down to press a wet kiss to his cheek.
Hitoshi nodded and giggled around his pacifier, looking at Shouta with loving eyes. And, God, if that wasn't one of the cutest things that he'd ever seen. As he crossed the threshold into his own little apartment on U.A. campus, he made a decision. He was definitely going to be filling out the paperwork to become Hitoshi's official caregiver.
