If it is not an allergy, you will want to get the food back in the diet as soon as possible since avoiding the foods unnecessarily may increase the risk of a food allergy developing. Upon a diagnosis from an allergist, seek an expert for treatment advice. Many treatments work better in toddler age children, so the sooner treated the better usually.
