If my child tolerates a new food, do they need to keep eating it regularly?

Yes. Once your child has safely tried and tolerated an allergenic food, it’s important to keep that food in their regular diet — ideally 2 to 3 times per week. Regular exposure helps maintain tolerance and reduces the chance of developing an allergy later on. If the food is eaten only occasionally, the body’s tolerance may lessen over time. Your paediatric allergist will give you advice on safe portion sizes when introducing new foods.
