I gave my 8 mth old some cherry tomatoes today for the first time and all around her mouth went bright red. It only lasted half an hour and she didn't appear to be in any discomfort. Now I cook with tomatoes from fresh or passata ot tinned at least 3 times a week and she has never had a reaction.
Is this an allergy? Is it possible to have an allergy to a food in its raw state and not when its cooked??
