Hi, my DS is 12 days old. We were in hospital for just over a week after he was born as he was small for his dates and was jaundiced. He is now breast feeding successfully after his tongue tie was sorted. When we were in hospital we were told to feed every 3 hours and to wake him if necessary. The last few nights he has been very sleepy, not waking for a feed and going beyond 3 hours since the last feed. When I do wake him he is furious and won't feed! It takes ages to settle him enough for him to have a reasonable feed. Is it ok to leave him longer and let him wake naturally? Or will he not be getting enough food? Thanks
