Here is a link to several presentations on preventing autism in future pregnancies. They were really helpful to me in subsequent pregnancies after my dd with autism. There is lots of information so they were a little overwhelming but I just took what I thought I could manage and incorporated it into my pregnancy and also what I am doing now with my kids as far as nutrition, medical care, etc.

Hope this helps someone!
