Hives 4-5 hours after eating peanut butter?
I have a doctors appointment next week regarding this but I wanted to get some opinions before I go.
My 15 month old son had a very small taste of a homemade peanut butter ball. Just the filling and it was less than a 1/4 of a teaspoon. He was fine until about 4-5 hours later. He got a red splotch above one eye that over the course of the next hour spread to the other side of his face. The splotches lasted overnight and went away by the next morning.
He was visiting my mom who was wearing a new lotion and who had also used a new laundry detergent.
My question is, could a peanut allergy cause a reaction that was that delayed or is it more likely to be her lotion/detergent?
Thanks for any and all input.
