Welcome to the forum. I'm new too. You said you were going to start chelating soon. Have you read information on Andy Cutler's chelation protocol? It is really interesting and I think it makes a lot of sense. It eased my fears about chelating and made me feel like I was doing it safely. I didn't feel safe doing IV chelation.
Can your son tolerate cashews and honey? If so, I have a recipe for sweets that is pretty good.
