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.
