We don't know what causes asd. We know it cannot possibly be 1 variable. I have a 34 y.o. son w/autism. He is great. Yes, he still has autism, it is part of who he is. But he has a good life, a good job, & friends - real friends. I was 18 y.o. when he was conceived, the dad was 19 y.o. That same dad has another son w/asd. It is not your "fault."View Thread
