Forced into this.

'Big Brother Shinsou.'

Shinsou woke up to hear soft babbles and Bakugo poking at his face. He groaned, not usually being up this early. As he opened his eyes, he saw his little 'baby' brother, Bakugo, looking confused.

"Bakugo?" Shinsou muttered, still trying to wake up fully. "What are you doing up so early?" Usually Shinsou wasn't awake at this time..

Bakugo babbled incoherently, looking both disoriented and a bit upset. Shinsou sighed, realizing he had to take care of his brother as his fathers were probably asleep.

Shinsou gently picked up Bakugo, cradling him in his arms. "Alright, squirt, let's see if we can get you settled down," he whispered softly, trying to soothe the little.

"What's the matter, Bakugo? Did you have a bad dream about losing your favorite toy?" Shinsou teased with a smirk, knowing how particular Bakugo could be.

He carried Bakugo to the kitchen, hoping a bottle of warm milk might help. "You know, for someone who acts so tough, you sure are a softie right now, I think I like you this way more.. besides the part that you're not potty trained" Shinsou chuckled as he prepared the bottle. Bakugo just stared up in amusement.

With the bottle ready, Shinsou sat down and fed Bakugo, watching as his brother's eyes began to droop with sleepiness. "There we go, little guy," Shinsou murmured. "Let's get you back to bed before anyone else wakes up and sees how cute and cuddly you are."

As Bakugo's eyes fluttered, Shinsou couldn't resist to have one last tease on the baby. "Just wait until I tell everyone about you waking me up for cuddles and milk. They'll never let you live it down," Shinsou said, knowing damn well he'd only tell his fathers.

Shinsou then creeped to Bakugo's nursery and carefully laid Bakugo back in his crib, tucking him in gently. "Sleep tight, little guy," he whispered, brushing a soft tuft of hair from Bakugo's forehead.

Just as he was about to leave the room, Shinsou heard a soft knock on the door. Aizawa peeked in, his eyes still half-closed from sleep. "Everything alright in here?" he asked quietly.

"Yeah, he's just a bit restless," Shinsou replied. "I think he's finally settled down now."

Aizawa nodded, stepping inside to take a closer look at the sleeping Bakugo. "Good job, Shinsou. You're a natural at this," he said with a rare, gentle smile.

"Thanks," Shinsou said, feeling a sense of pride. "I guess it's not so bad taking care of the little guy."

Aizawa chuckled softly. "Just wait you deal with a diaper-change or a tantrum, then we can see how you feel."

Shinsou did a puking motion at the other. "You'll never see me dealing with changing him, maybe a tantrum though.. if that even happens because I'm the best brother ever."

As they both quietly left the room, Shinsou couldn't help but feel a growing bond with Bakugo He was super cute.. even if taking care of him was a bit annoying."

Shinsou decided it was time to get some rest himself as he deserved it. He barely made it to his room before stopping at the couch before exhaustion took over, and he passed out right there.

Aizawa, who was just trying to get a glass of water for himself, noticed shinsou sprawled out on the couch, shook his head with a small smile. "Looks like everyone's getting their rest tonight," he murmured, grabbing a blanket to cover Shinsou.

As the night continued, the house was filled with a peaceful silence, with everyone finally getting a chance to recharge for whatever the next day might bring.

It was the next morning, Mic and Aizawa had to take Eri to play therapy which they both were heavily involved in, leaving the baby with Shinsou.. if he was even a baby anymore.

Bakugo woke up to the sound of a camera shutter. He blinked sleepily, only to see Shinsou trying to take a picture of him in his crib.

"Seriously,eyebags?" Bakugo said loudly, feeling a wave of annoyance. He wasn't little anymore.

Shinsou quickly put the camera down. "Sorry, little guy. You just looked so peaceful, I couldn't resist," he said with a sheepish grin.

Bakugo huffed, crossing his tiny arms in a way that almost looked like his usual stance. "I'm not little anymore, and don't fucking take pictures of me while I sleep.. weirdo."

Shinsou chuckled softly. "Alright, no more pictures. Let's get you something to eat, okay? Even if you aren't feeling little, it's still important that I feed you."

Bakugo's annoyance faded slightly at the mention of food, and he allowed Shinsou to lift him out of the crib. His stomach growled and with Shinsou carrying him to the kitchen.. the small feeling couldn't help but to return.

"Shin," Bakugo said, drawing the other's attention once more.

'Not little my ass..' Shinsou thought, staring at the other. "What's up?"

"Hungwy.." Bakugo grumbled, in need for something in his belly, Shinsou blinked dumbfoundedly in response. "Yeah, I'm aware, that's why we're in the kitchen silly."

Bakugo dramatically rolled his eyes, he was feeling about 3 right now.. not too young like he usually is. He'd point to the Cheerio's. "I want that."

"Say the magic word then,"

"Please." He'd say as he reached for it; he didn't really care about manners.. he just used them to get his way which it did indeed work as Shinsou was pouring them into a bowl, then pouring almond milk into it.

Bakugo immediately clapped his hands, feeling ontop of the world.. not only was he being held, but he was also using shinsou as his servant. I mean.. he was a little prince though so he did deserve this treatment, maybe they'd even have a tea party later in the day?

A lot of people wanted Shinsou and Baku content, so here you go! I hope this was cute! Next chapter should be half Baku and Shin spending time with eachother and then of course something else.

Thank you for reading! I hope you enjoyed! If you did, I actually just published a new book.. just a bit different as it's about Bakugo getting hit with a de-aging quirk. I don't want to spoil too much, but it's basically Mic and Dadzawa as his caretakers! If you would read, it would be very much appreciated as it's been my main projects recently. 3 chapters are already out!

Thank you for reading, ideas and feedback are very much appreciated.
