Two times this week Nathan has told me that his tongue itches. One time was while we were grocery shopping, he didn't eat anything, he was just sitting in the cart. He started grabbing his tongue and was almost trying to tear it out of his mouth, I immediately gave him some Benadryl and he was fine. It was scary, it may have been something he touched on the cart.
Then tonight while we were eating at a restaurant he said his tongue was itching again. It is food that he has eaten before but you never know if there was cross contamination. My husband said that he just says that, so I waited a few minutes to see if I would see anymore symptoms and I didn't - Nathan kept eating so I held off on giving the Benadryl. He was fine.
