<s>[INST] My baby keeps dry heaving, he s 3 weeks old I m wondering if it s reflux or just a dry throat as he sleeps with his mouth open, there isn t a pattern to him heaving it s just now and again sometimes he brings up milk but other times its just the heaving, he is very good with his wind! It comes out both ends a lot! I m worried he s going to choke while he s asleep.. [/INST] Hi...this happens in kids who are over weight and re being over fed. They tend to regurgitate the feed which is excess and that's what comes out. If he is otherwise active do not worry.Regards - Dr. Sumanth </s>
