Since my milk came in, Sebastian has been feeding around every 1.5 - 2.5 hours, often sleeping mostly between feeds, as I guess is normal for a newborn. I just wondered if I should wake him up to feed him if he sleeps for longer? The other night I woke him up because it was really hot and I didn't want him to get dehydrated but on a normal night is it OK for him to sleep for about 4 hours without waking?

tia,
