The Gag reflex?

We live in Ireland so we have to listen to the podcast each week. My wife and I really enjoy it as we generally listen to it while eating breakfast on my day off. The problem is that my three-year-old son always gets sick while eating breakfast. I just assumed that it was because he ate too many pancakes. We were listening to the podcast form 3rd July and you mentioned that you take a break to allow listeners to recover their gag reflex. My question is, is my son getting sick from eating pancakes or does he suffer from the gag reflex?
