I was actually pretty shocked that my kids had metals in their systems as we don't vax. I said, nope, not possible. But, then I realized that it sneaks in through our foods.
ahhh long topic
A little OT, but when ds was 2 we learned that he had mercury in his muscles and spine, and I had it in me too. We got it out homeopathically, and wow what a change we saw in ds -- the poisoning was subclinical, but he became so much more physically capable after (climbing more, etc). Anyway, we got it when I was pg with him and was working in a dental office -- ambient mercury . And yes, a long topic.
