My son has FPIES and has thrown up more times in his barely 3 years than I have total in 5 of my lifetimes. Point is, now he is throwing up for unrelated things. Colds/congestion, sore throat, other just normal stuff... he thinks it's bad and he turns it into a gag (especially at night/nap) and throws up. Anyone else have this problem? What has been done to change this frame of mind in a young one?
