We have started our difficult child on a glutn/casien free diet for the past week now, and have been very strict to what we have educated ourselves on. However, we have seen no improvement , only constant anguish in our difficult child. He protests every new gluten/casien free food that we give him. Endless crying and tantrum. His amount of consumption has decreased dramaticaly. No noticed change in his attitude or behavior. I have heared from his school teachers that urine tests from a specialist should be done to evaluate wheather or not this diet will do any good. I have debated if we should contiue with this diet until testing, but we have no idea where to find a doctor to provide these services. Our local pediatrician seems to know very little regarding autism, and we live in a fairly small town with no other choices. We were wondering if anyone had any other insight as to where to start, or where to find the right doctor to do the testing. Cheaper places to purchase theese foods would be great too!
