She tried fish for a second time and complained about the same thing, so we figured she was probably allergic to the fish.
I have seasonal allergies and for me an allergic reaction looking like swollen eyes, runny eyes, runny nose, sneezing, and stuffiness.
I mean other than the original mad dash to the ER the first go around, we eliminated what we thought was causing the reaction, which was peanut butter and anything peanut related for our oldest daughter and fish for your youngest.
My oldest daughter has food allergies and my youngest has a mixture of food and environmental allergies.
