I don't wake up my little boy to eat.
He has slept through the night since the day/night he was born (except for a few nights). I have never woken him up to eat (even when he lost almost a pound of his birth weight). He is 5 weeks old now and he weighs 10 pounds 5 ounces.His doctor is pretty happy with how healthy he is.
During the day it seems like he doesn't eat very often, but maybe I'm just tired because he is on track with everything. :)
