Hi my baby boy has just turned 3 months old, he is currently on aptamil pepti for milk allergies. The past few weeks he had been constantly turning his head left to right when feeding so I changed teats from MAM to tommee tippee. He's using the vari flow teat so can manage the speed of the milk coming out himself but he downs a 6ounce bottle in under 20 minutes! Is this bad for him? Any suggestions how I can maybe slow it down if needs be? He burps fine so isn't swallowing much air I just don't know if I should worry or not? Thanks 🙂
