Hi, My 3month old baby is on bottle feedings,i purchased anti colic Philip Avent bottle 2months before but nor unfortunately the teats got damaged due to which I had to purchase another bottle that is of bonne bottle company . Both teats(nipple)shapes are totally different. through bonne bottle she sometimes latch nipple but cries alot and other times do not latch nipple,so crying is because of changing the nipple shape,so shall I again go back to Philip nipple or should continue try with this bonne bottle. In how many days can she get a habit of this new bonne bottle?
