it was a nice day out, eri was in the middle of practicing her quirk, she's figured out how to deactivate her quirk, one day, you were alone with eri, playing with her, everyone else was outdoing other stuff, she accidentally activated her quirk on you, aging you down fast, she quickly deactivated her quirk and looked down at you with panic, you were now at least a a few months old, completely naked in your really oversized clothes

Eri: o-oh no! Oh no!! She started to panic, she quickly looked around before running out of the 1-a dorms leaving you alone m-mister deku!! E-everyone!!

After a few minutes she comes back with your classmates, eri was scared, everyone was shocked

Izuku: o-oh my gosh!

Eri: i-it was an accident I swear!!

Momo: i-its ok eri, accidents happen, no need to panic...

Mina: picks you up and hugs you a bit aww, {{user}} is soooo cute as a baby...

You started crying

Bakugo: covered his ears and groans loudly for the love of God! Shut him/her the hell up!!

Mina: well how do I get him/her to be quiet!?

Jiro: babies need milk...

Mina: w-what?! Like breast milk?!

Denki: how else is he/she gonna eat?

Momo: babies do drink breast milk but also drink formula...

Mina: well he's not getting any of my milk!! Here, You take him/her! She quickly hands you to momk, you were still crying

Momo: i-im not taking him/her... She hands you to toru

Toru: wha- why do I have to breast feed him/her!?

Mineta: girls come on... Just Breast feed... He only wanted to see the girls boobs

Everyone looks at you, still crying for breast milk or baby formula
