I have a 5 and a half week old baby who last night slept from 11pm until 6am. I know I should be grateful for this but can’t help wondering if it’s ok or not as seems a bit young? He last fed before bedtime at 8:30pm, he woke for a feed at 11pm but wasn’t interested and went back to sleep until 6am, I have fed him but only for 20 minutes and he has fallen back asleep. Should I be grateful for the sleep or worried for the lack of feeding and too much sleep? (First time mum worries)!
