My baby is 6m old, he was in breastfeeding and cup feeding. We didn’t give bottles for 4+ months thinking it may cause nipple confusion. Bad luck after 4 months when we tried to introduce bottles for formula he is not taking bottles. He seems hungry but not drinking from bottles he is drinking 10-20ml and refuses to drink from bottle. Any suggestions Like how to make him take bottles. He refuses and not drinking he simply bites the bottle nipple and stops feeding after 10mins pushes bottle away.
