My LO is 9 months old today and eats three meals a day and snacks in between (he really never stops eating 🙈) but he hasn't really been drinking his bottle 🍼 (he's on Formula) would it be bad if I cut down on the amount of milk he gets ? (Breakfast,nap,bedtime). He doesn't seem to be a huge fan of juice but will drink water so no complaint 🙌🏻
