What to do about Alexander

One of the questions that has been coming up since I've decide to go gf is regarding our 11 month old son, Alexander.  Since gluten intolerance is hereditary, if I have it, he has a chance of having it, too.  Do we worry about him?  He's had already had wheat, and hasn't had any strong reactions.  But, according to the information from Nadine, the Gluten Free RN, not everyone exhibits symptoms like I have.  In fact, I didn't have the digestive problems until my mid-twenties.  But, looking back, I probably have had anemia my whole life.  Do we just wait and see if he is anemic, too?  So many questions, no good answers yet.
