My child is getting hives consistently

A. Hai good morning !! Any symptomatic hives like itchyness along with swelling or only allergic reactions. Observe the frequency of getting hives,symptoms and behind reasons like any food allergic reaction . Because few body types have allergic reaction to milks,diary products,nuts,egg ,poultry ,sea food. Next time while getting rashes observe baby diet earlier day,before hours whether he had sea food,nuts,diary products or so. Give food like trial and error and list out the food items causing this and avoid for some days. Consult Doctor about this.
