Sleeping baby

Franki

Hi all. My boy is 5 days old and every night he's been sleeping from 1am-730am-ish. Now don't get me wrong, I'm not complaining, but I was told at the hospital they shouldn't go more than 4hrs without eating...so am I supposed to wake him up to eat? Be has his first doc appointment today and I plan on asking, but I figured I would ask some other mommies too.
