I'm looking for a story I'm sure I read on Ao3. Basically, Loki was fighting the Avengers, and I think a spell backfired on him turning him into a little kid. The Avengers took him in and Clint ended up being the parental figure to him. I don't remember the reason, but I think the Avengers were having Loki do something, and every time he did, the adult Loki personality would come back a little more. In the end, the true Loki personality decided to basically kill himself as long as they promised to always love and protect the nice kid Loki. I also think there was a scene in which the Avengers had dressed Loki up in Thor pajamas.
I know it's confusing, but that's the best way to describe it. I really liked that story and hope someone knows what I am talking about. Oh, and it's not the story in which Phil/Clint raise Loki. This is purely Clint being solely responsible for Loki.
Thank you to any and all help.
Edit: Found! by the amazing jejo763 The story is Amateur Theatrics and the story I mentioned above is the Kid Loki Series
