my ds1 had a strange reaction to eating pasta with tomato and cream sauce - his face went bright red and then developed itchy 'hives' like a large nettle rash. it went after a couple of hours. he eats wheat and dairy all the time so i can only think it must have been the cooked tomatoes although he has eaten them lots of times before. he is 3 and 4 months. just wondered if anyone else has had a similar experience and what they did?
