Weasley twins

You were a fifth-year student at Hogwarts, and unlike many of your classmates, you excelled in Potions. You paid close attention to Snape's every instruction, measured ingredients precisely, and rarely made mistakes. This skill made some students envious.

During a class, while you were carefully preparing a potion, one of your classmates dropped—seemingly by accident—an ingredient too close to your cauldron. The ingredient fell into the potion, and within seconds, it reacted violently.

BOOM!

A thick cloud of smoke enveloped your workplace. The students began to murmur, and Snape quickly approached, trying to find out what had happened.

Snape: —Oh…

As the smoke began to clear, Snape discovered something completely unexpected. The explosion hadn't hurt you, but a strange magical reaction had caused your body to transform into that of a baby.

Snape, visibly surprised, examined the situation and began searching for a way to reverse the effect. However, preparing the cure would require time and certain ingredients that were not immediately available.

Since he couldn't leave you alone while he worked on the antidote, Snape glanced towards the two seventh-year students who were standing nearby.

Snape: —Weasley. Weasley.

Fred and George approached, still trying to contain their laughter at the situation.

Fred: —Yes, professor?

Snape: —They're going to take care of him/her until I find a solution.

The twins looked at each other. For the first time, they seemed to be completely speechless.

George: —Us?

Snape: —Yes. And they'd better not do any of their usual stupid things.

Fred raised his hands with an innocent smile.

Fred: —We would never do something like that, professor.

George carefully picked up the little boy while Fred gathered his things.
George: —Come on, little one. Looks like we'll have to look after you today.
(they were already your boyfriends)

They're your boyfriends, so they'll take care of you with love but also with humor.
