I have been wondering that.

Our first house may have been when he started accummulating it. Then, after that, he puts everything into his mouth, including sand. We try to keep sand and dirt out of his mouth, but usually he gets some in before we move him from that environment.

I still think he suffered a tremendous environmental insult. (mercury) Because I have videos of him talking and playing up until the vaccines. Then I have inconsolable crying. And I remember the reaction to the vaccines. (he got very sick, then wasn't the same, and continued to regress)

But I want to get the lead out! It causes permanent neurological damage and/or mental retardation. He doesn't have MR yet. So I hope they hustle on these blood tests and chelation.
