My son was diagnosed with Autism when he was 4 years old.  When my wife was pregnant, she didn’t take Tylenol, because my wife’s pregnancy was difficult and her doctor advised against it.  My son spent a year in ABA therapy.  His speech greatly improved and he worked on potty training.  He made a lot of progress and is able to attend kindergarten, while also attending a special education classroom.  I don’t believe that Tylenol causes Autism.  I think it is genetic and passed on to children.  My wife and I suspect that my older brother is on the spectrum.  However, Autism was not as prevalent in the 1980’s when we were little kids.  So, my parents never got my brother diagnosed.  Autism is a condition that involves developmental delays: it’s not an illness that can be simply cured.  It requires therapy and understanding and compassion.  My son is bright, healthy, and happy.  I have no idea what his future holds, but I know that he won’t let Autism hold him back.
