My little guy is 12 weeks old and has been on a 3 hour schedule for 6 weeks now. He is breastfed only. Sometimes he will only eat for 6-8 minutes and then he refuses any more. Usually he eats 20-30 minutes. Does this mean I should be spreading out his feelings more, to like 3 1/2 hours or 4 hours? Or is it normal for a baby to not be as hungry for some feeding throughout the day?
