Hi, I'm looking for a deaged Sam fic with 12 chapters: where a witch gets revenge on John by turning Sam from 12 years old to 2 years old. Sammy doesn’t acknowledge John as his father (and sees him as his grandfather in later chapters) and John thinks he’s a trashy father. But the 2 years old firmly believes that teen Dean is his true father and the story goes on with Dean having to play Sammy’s father once again. That’s all I remember.

Edit: Thanks for trying. But I think I'm giving up.
