Baby-Charlie fic: early development/diagnosis of genius

[endersgambit.livejournal.com]

Hey guys. This is my first post on Livejournal! Anyway, I'm looking for a fic I remember bits and pieces of. It's a kidfic, at least in part because at one point little Charlie was being assessed by doctors and one of the doctors didn't like the way Charlie arranged the toys by size. He said it might mean Charlie was autistic, but Alan then called to Charlie and when Charlie came running to him with a big smile and wanting a hug Alan insisted an autistic child wouldn't do that. That's all I remember. Sound familiar?
