Yes, I know this is long. But its an awesome fanfic of the Sherlock characters as professors at Hogwarts!<-----omgomgomg I thought he was on the Hogwarts train before I even clicked on it! I LOVE this.
Awww :) the only flaw with this is I'm pretty sure John would never leave baby alone with Sherlock. He'd be incredibly protective of baby, but that wouldn't change the fact that he's flighty and oblivious about common sense things.
