While feeding, my son tends to push the bottle out of his mouth with his hands or turn his head. I thought maybe he wasn’t hungry at first, but If I don’t bring it back to him he screams. I then started to think maybe the flow was too fast and he was trying to catch his breath but I notice if I lie him back with his head hanging back he drinks it with no issue and doesn’t move the bottle. Does this sound like a esophageal/airway problem? In the beginning he did aspirate at times with the size 0 nipple. After that slowed down and we felt comfortable, We finally moved him up to the 1. He started to get frustrated with the size 0 because the milk came out too slow. He’s been using a 1 for quite a few weeks now but this pushing the bottle away thing have only recently started

Have anyone experienced this?
