I will tell you, my almost nine month old SW CAH son has a gag-type reflex; once I have called the paramedics, and just yesterday the nurse at the clinic, since he seemed to be gagging on something, like, he has spaces between breaths, and drool comes out of his mouth, or spit up. I didn't know if he was choking on his drool, or what. It was interesting to see others with this same problem.
