okay my baby will be two months tomorrow.. she goes through quite a bit of bottles in a day.. I make them 6 oz. and she will sometimes eat 3 oz. or 4 .. or sometimes (rarley ) the whole bottle... its wasting a lot of formula too. idk what to do.. and what about tooth decay what should i kno about proper bottle feeding to prevent that ? also when i feed her somtimes she wants to eat every hour or less just some questions thanks!
