Have you ever read the book "Is This Your Child?" by Dr. Doris Rapp. That is where I found info that confirmed for me that the behavior and digestive problems that our son was having was from dairy products. We put him on a diet without any dairy products and even he noticed a difference. He also tested negative to the skin tests and that particular Dr. didn't want to touch the idea of dairy being the problem with his behavior. She said that "there is no scientific evidence" and that if I believed that dairy was the problem, then I shouldn't give it to him. Luckily our family Dr. took the evidence that I showed him seriously and we now say that he is, "Allergic to All Dairy Products." I know that many people would say that using the word allergic is not correct but it's necessary for people to take the situation seriously. If you've ever had a child who has one of these uncontrollable fits, you would want to do everything to make sure that they or the people around them, don't have to go through it. Even using words that are not technically correct. Heidi L. : )
