I have a 4 week old who only nurses about 7 times a day if I wake him up every three hours during the day to nurse. He goes anywhere from 4 to 6 hour stretch between nursing at night. My peditrician says to wake him every 3 hours during the day and every 4 at night. When I do that he seems fussy and does eat as well. Is it really necessary? He is gaining weight fine and poops and pees plenty. Help everyone is telling me something different.
