It's true that many children are toxic with mercury. First they get mercury from the preservative thimerosal in the vaccinations they are given, and also, if mom has amalgams in her mouth during pregnancy, the mercury can pass through the placenta into the child. Between these two factors, they can already have a big enough body burden to eventually cause symptoms. Some children are developing autism and other developmental delays as well as ADHD from these issues. However, it is important to make sure that they do not have a copper problem which can cause the same things. Mainstream doctors only recognize copper as a problem when there is liver disease called Wilson's Disease. However, elevated copper can also cause these types of problems even without Wilson's disease. You need to find a special doctor who will run their red blood cell copper to and do a hair analysis to determine if there is a copper problem. If that is excluded, then you can work on the mercury detoxification which I would do by following the protocol of Andrew Hall Cutler "Amalgam Illness Diagnosis and Treatment" which you can purchase right here on this website.

Good luck
