I didn't know I had any autoimmune diseases, then. And I do know that I have kids who do not have Autism and I know others who have autoimmune disorders far worse than my own who have children who are neurotypical.
My husband had traits and I seem to be pretty much AS, although I don't have a diagnosis.
We have four children. Two have ASD. Two seem to be fairly NT.
I had enough trouble dealing with "refridgerator mother" theories, which are still floating around the medical community.
