The Amish and Autism

According to a Government study 1 in 100 children has an Autism Spectrum disorder.  As a mother with a child who has an autism spectrum disorder it really does make me wonder about the autism vaccine connection. Yes there are some Amish who vaccinate, but the numbers are lower. The one child that I  know of that has autism who is Amish was adopted. I am not saying that there is not an Amish child without Autism I am saying that it is almost non-existent. And according to the governments numbers then there should be way more Amish running around that have and autism spectrum disorder. So really what are we doing that is so different then the Amish.  We need to take a closer look at why their children are not getting the autism spectrum disorders and ours are. Mainstream science says that autism is from a genetic disorder but I am not totally buying that.  My personal belief is that there may be a number of different factors that could cause a child to have autism. So, again I say what can we learn from the Amish?
