<<Disclaimer: Verify this information before applying it to your situation.>> Donna, There is a really good paper, by Lisa Lewis (one of the list owners) that talks a great deal about gluten and casein and the possible effects of these on developmental delays. (You will probably get a note from one of the listowners on how to access the archives; and most if not all of the paper is in there). My son just turned 4 and is also 'mildly autistic' (my words). The doctors call it PDDNOS (Pervasive Development Disorder, Not Otherwise Specified) or MSDD (Multi-System Developmental Disorder); he doesn't talk very much yet, so we don't know if he has had an stomach pain. The paper talks about the possible toxic effects of gluten (protein in wheat and other related grains) and casein (protein in milk). My son has reacted quite well on a gluten and casein free diet. See Bette Hagmans "Gluten Free Gourmet" or "More From the Gluten Free Gourmet". We found both of these at our local library (based on the very kind suggestions of the members of this list) and have had such good success with both of them that we went and bought our own copies. One of the things you might find (based on reading Lisa's paper) when you stop giving your son gluten and casein products is that he may get worse for a period of time. (If I understand Lisa's paper correctly this is actually a drug-type withdrawal). We noticed this with our son. He has always been a very pleasant and happy kid. For about 2 months he would have almost daily tantrums, bang his head a lot (which he did a little before, but it was more noticable) and bite people when he was frustrated. Now (about 4 months GF/CF) his tantrums are much more infrequent, he doesn't bang his head much anymore and I can't remember the last time he bit anybody. Kevin J.
