Okay, but, other than the baby contracting it from the mother, we have another issue we need to address: Vaccines, which contains the mercury preservative thermisol. Babies and kids are pumped full of vaccines which do nothing to fight off what they are meant to. So Megghill most likely not only had a mercury issue before giving birth, but perhaps she was also vaccinated beforehand, and later the baby got vaccinations.
I have read in the book "it's all in your head" that there are individuals who are highly sensitive to mercury. I may be one. I'm not saying you are though.
