So much info, so little time....

I've been hopping around the internet just trying to get an overview of things. I'm not wanting to dive right in just yet. I'm still trying to find my bearings. There is just SO MUCH I need to learn. I feel like it'll take me a lifetime to learn it all, but I don't have the luxury of taking my time. We need to get on this NOW. My head is swimming with all these new concepts and concerns. Right now, first and foremost in my mind is the role of diet in all of this. Since Jesse first started on solids at 6 months of age, I knew something was going on. I knew it. He had food intolerances right away. He got hives from oatmeal. He had a bout of the nastiest diarrhea I've ever seen for about 10 days, even though he wasn't otherwise ill. He had allergy testing done and had no food allergies. He was also screened for celiac disease, which came back negative, but now I'm wondering about the validity of that test. He hadn't been eating much food with gluten for very long before being screened. And now I'm wondering if his initial language regression after his first birthday was related to the introduction of cow's milk into his diet. I know it all sounds crazy, but at this point I'm willing to investigate anything that might be causing this and I'll do anything to make it better.
