Egg Allergy

I baked Lemon Meringue Pie today and it turned really good.What was not good about my baking was when our daughter had some skin rash from the meringue I prepared. My husband and I let her lick the spatula covered with raw meringue. We did not expect that she will have skin reaction since we give her scrambled eggs or egg omelet sometimes.The rash was all over her mouth, neck, few spots under her eyes and ears. We could not give her Benadryl until the doctor advice us to do so. Good thing it was not that serious but my husband take it seriously because allergy issues run in the family.
