"My wife and I don't allow our 7 month old to watch TV. We do think there is a connection between Austism and watching TV. I mean, what else can it be?" Genetics. Autism is an organic disorder. I think what will be found is that wether or not a child develops a disorder from the genes they've inherited is impacted by outside forces, so it will be a combination of factors. If a child has inherited the gene and is plunked in front of a TV all day, it will likely exacerbate the condition. Perhaps getting the vaccine with a protein in it that the child is sensitive to can act as a trigger at a critical point in their brain development? Nobody knows yet, but your approach of avoiding the idiot box at this important time can only help your child.
