i did that last week when i was in the hospital he went 7hrs with out eating and his blood sugar went down so ever since i get scared and just wake him up lol. just for now that he's still alittle small. yes well i try but since he has a hard time latching i pump and bottle feed at night. i see a lactation nurse she says the reason he doesn't latch its cause my boob & nipple is to big for his mouth when he gets alittle bigger it hopefully will get easier for him. But he does okay with a nipple shield
