Both of my sons have Aspergers. One is pretty high functioning, the other...well, maybe moderate at best. Looking back, I don't know how I got through it. They started off really as more classically autistic being called plain PDD (not even with an nos added), yet no one back then ever would say the dreaded "A" word. Son #1 was in services by the age of 10 months, son #2 by the age of 5 months, so in one sense the services we got them I feel "graduated" them from autism to Asperger dxes later on.
This was way back when (sons were born in 90 and 92. We didn't even know about stuff like ABA. We did OT, PT, social skills groups, sensory integration stuff, even chiropractic care, developmental preschool, plus both had very lare summer birthdays so they were 6 or close to 6 when they started K. They got on IEPs right away and continued services in school.
In Jan 1999 at the U in Seattle, we were one of the first families in a study with 2 or more kids with any form of autism. It was in this study that they said to me, oh by the way after all this testing (they tested both my husband and me as well), did you know *you* have Asperger Syndrome too? I am half considering doing one of the studies they have going right now for adults with AS that involves doing an MRI of the brain and facial recognition (an aside).
Btw, when my sons were little, we lived in Kent and their therapy was at the Children's Therapy Center there.
