If he has had 2...perhaps the second one is not working again. He may also destatting due to stress. Any change in his position or a sound that he is reacting to in the room.
He have had 2 fundoplication done, one in 2007,and the other in 2010 I have thought about that, also, but I am so discourage because I think the doctor thinks that I am worrying to much ,that why I am seeking other info
Gerd, would be my first thought. Premies seem to come with it. If the stomach acid gets in the throat it can cause breathing problems. It can also get in the nose and ears. Have the Drs. mentioned that??
