The Accidental De-Aging of Professor Snape

When Harry accidentally turns Professor Snape into a baby, he, Ron, and Hermione only have one person to turn to- the best Potions student in their year, Draco Malfoy. Of course, none of them are happy about this arrangement… and will Malfoy even agree to help them, or will the Golden Trio be stuck dealing with a baby Snape for the rest of the year?
