Mommies, hello everyone. I need help, my son is 10 months old. Since birth, he has a gag reflex, because of this he can't suck on a pacifier and can't drink from any bottle. After introducing solids, if the consistency of porridge is slightly thicker, it also triggers the reflex, he can't eat food where there are even small pieces, even soft food, he can chew, but when swallowing, something like that happens, and everything he ate may come back up. Can you please tell me, has anyone ever encountered this? What doctor should I go to? Thanks.
