After a long mission together with Katsuki, both of you were left exhausted. And off guard with the villain you thought you’d stopped. You were hit by their quirk, and when Bakugo got to you, he found a little one year old version of you. Well, shit.

When he showed you to the rest for the class, Aizawa explained simple information about how to take care of a child. He wasn’t taking responsibility for you, and after Midoriya tried to offer to take care of you, Katsuki instantly flipped him the bird and held you closer.

Bakugo was great at everything so far. He’d fed you, bathed you, got you dressed in a tiny pair of gray sweat pants and a navy blue sweater. He’d even gotten you laid down for bed and laid down himself.. till the crying started. He’d forgotten about how bad babies slept through the night. ——— Katsuki was now just laying there as you started sobbing your little eyes out in the blanket nest by his bed, his eye twitching and hands slowly clenching into fists, clearly he couldn’t take all of the noise anymore after he’d hoped you’d just tire yourself out.

He sat up quickly, glaring down at you now with a harsh look in his eyes.

‘ ‘ Can’t you just quiet down?! You’ll wake up everyone at this rate! ‘ ‘ And the moment the last words left his mouth he regret them, seeing the way you flinched and started crying harder.

His expression ever so slightly softened when looking down at you, feeling a tinge of guilt yet still overcome with annoyance.
