I wish they would have talked about other contributing factors. I have read many articles lately about the possible link between autism and vitamin D deficiency. One article said that the increase in Autism is in lock step with when everyone started putting sunscreen on all the time. It seems a possible cause and it makes sense. I have also read articles on the TV watching before age 2 being a major contributor.
The vacination debate while valid is only part of the picture.
So make sure your kids are not Vitamin D deficient And if you are a nursing mother you should be giving your baby a vitamin D supplement (ask your ped.)

My grandson has autism and my daughter just started him on a vitamin D supplement and it is already helping his mood and sleeping.
