Letting baby sleep

Olivia

So I never know if I should wake my baby to feed or not. Doctor said I could skip one feeding but don’t skip 2, but doesn’t that mean don’t let her go more than 4 hours without eating or 6 since they are suppose to eat every 2-3 hours. And what about when she naps during the day...what do you do? New mom with a 2 week old.
