Has anyone else developed a new food allergy while pregnant? I have never had a peanut allergy, but recently, if I eat peanut butter, I'm starting to get the very early signs of anaphylaxis (itchy mouth and throat). I've stopped eating anything peanut related as soon as this started to happen more than once. If this has happened, do you now if these allergies will follow you throughout life? I love peanuts, so this would be very sad if it's the case.
