You are not alone and protecting your children from heavy metals is noting to be weird about. Many parents struggle with this and the more they dig into the info the less they want to place these chemicals in their children. This was a brave post and I commend you for coming forward. Just remember you are not in this along. We all struggle to learn what is true and false in this world and more often than not, we find that what we thought was right is the exact opposite. Thanks
