So my baby is going to be 14 weeks old in a few days. He eats 4.5oz. The past two nights he’s been waking up every 2-3 hours. Like he’ll wake up about every 3 hours to eat mostly his whole bottle but at one point he’ll maybe only have half or less. But for the past month once he has his last bottle he sleeps about 6+ hours before he gets up again. So not sure why hes doing this now. Because he also just gets fussy and he’ll fall asleep and about 15-30 minuets later he wakes up again just being fussy. He’s not bad but he just keeps waking up like that. I’m not sure why or what to do about it. I think I’m going to try giving him 5oz, he’s just always hard to tell because when I up his formula he like never eats it all so I waste a lot of it. But not sure if that’s going to help his fussiness at night or not. Anyone have this problem?
