FTM and breastfeeding. Baby 4 and half weeks old. Born 6lb 14oz. Has been gaining weight, even gained for the first time he was weighed when most babies lose weight. He’s been a really good sleeper since birth, the first week we were waking him every 3 hours to feed. Not always but having to wake him a few times. He’s still good with his naps through the day, waking himself and letting me know he’s hungry. Last weigh was a week ago and he was 8lb 1oz. I feel him between 11pm and 12am and want to let him sleep as long as he wants to. Last night he woke me at 5am and fed both breasts and back to sleep. Partner disagrees and wants me to wake him in the middle of the night to feed him. Baby has PLENTY of wet and dirty nappies. Am I wrong to follow babies lead for feeding now? Should I still be timing feeds?
