G.B.
I am certainly not an expert but the few kids I know that have had various degrees of it had perfectly normal parents with no history of autism or other mental illness.
THE POSTER BROUGHT UP MENTAL ILLNESS, NOT ME.
"His sister also has signs of OCD and anxiety, as does my husband".
She implied the other couples mental health and possible genetic tag for Autism were hindering her from choosing to have another child. I don't think the sisters mental health issues have anything to do with Autism to begin with but evidently this poster does so I answered her about that component specifically.
