So, my son will just randomly cough and vomit. Typically it is associated with eating food. He is 2 1/2 and been on solids starting at 6 months so it is strange. For instance today we were at dland and he was eating his popcorn when he coughed and vomited three times. Sometimes he doesn't even cough and he just vomits. It isn't associated with being sick because he is just fine before and after.

Unfortunately though when he does this he gets sent home from preschool which is difficult for us.

Anyone else's kid do this? Do they grow out if it or could there be something wrong with his eating?
