i think vaccines and genetics get too much focus when it comes to autism causes.
What else do you think causes autism? What have you dug up through research? Hopefully this thread will lead some pregnant mommies to do some research.
So, here are things i would avoid if possible:
anti-depressants in pregnancy
antibiotics - both in pregnancy and early life
here are other connections, but I do not know enough about them to judge:
-live near a very bust street
-have older parents or older grandparents - particularly fathers
-anesthesia in very early life
-acetaminophen, particularly in conjunction with vaccines
