Yesterday I was called by my daughter's daycare stating that she had a rash. When I arrived, the rash had disappeared from her face and was now on her stomach. We went to the doctor and he claimed it was a food allergy. The only thing she ate at lunch was wheat bread. She has been eating cheerios, baby cereal, gold fish, cookies, etc. for months. She is 17 months old and this is the first time she has actually eaten a full piece of bread, let alone wheat bread. Can a food allergy all of a sudden appear even though she has eaten wheat based food in the past? Or, could it possibly be that it was full wheat bread? We go back to the doctor next week for a follow-up for an ear infections, so I'm going to ask to do a food allergy test. I'm new to food allergies; they do not run in the family, so I am extremely confused by this.
