And I'm not dismissing your grandson's condition, but it wasn't classic autism because it got better. There are all sorts of developmental disorders that are not autism but involve late speech, withdrawal, and gait abnormalities. In fact, if you leave out the gait abnormalities you could be describing my second child. He got better too.
It is a waste of time and money for us to keep beating our heads against the wall over an exploded theory.
This thread has taught me nothing. It’s been a total waste of time. It’s as though the condition does not exist but I know it does.
