Hi, my name it Toni, I m 30 year old mother of a 6 year old son who has recently been diagnosed with PDD-NOS, I am a recovering addict of options and benzodiazepines, I have never spoken a wordof that while I was pregnant with my son until today. My 1st question is, do you think that my addiction to options & benzos caused my son s disability:(??? I feel TERRIBLE ! There hasn t been a single day I haven t felt guilt knowing what I may know now. And if not, what is the chances of having a child with autism or PDD? How does that happen?
