you seem to have forggoten that Harry has a house that Sirius left him and that his parents left him quite a fortune in Gringotts. He could physically care for a child.

Except that at the time of godfatherly appointment, Grimmauld had been completely compromised and Harry had no access to Gringotts as himself, as he was Wizardom's Most Wanted. If he'd tried to access his vaults, they would have jumped all over him.

I finally finished it. I was trying to draw it out. I'm still moping that this is the last one... ^__~
