My daughter asked an interesting question today. She wonders if anyone has ever done a study to see if there is any correlation between kids on the autism spectrum and their moms enduring trauma/abuse during pregnancy. Perhaps including questions about how closely the baby adhered to the recommended vaccine schedule.
Anyone heard of such a study?
Read the subtile 'Early life Stress'
If I understand it correctly it seems you can effect a fetus in pregnancy. They don't mention autism, however.
