I know it's been a while now since you posted this, so I'm curious to know how things are working out now that you have a diagnosis? My son was diagnosed with Aspergers in 2000, and while I think he actually has PDD-NOS (another diagnosis on the autistic spectrum), it was such a relief to have ANY diagnosis that accounted for his autistic traits that I was thrilled. We had spent years trying to understand why he had echolalia, perseveration, noise sensitivy, and OCD-like behaviors, but all anyone could say was that he was "too social to have autism." It's been a godsend to have the definitions of what constitutes the autistic spectrum opened up to reflect reality.
I know a lot of people feel labels are "bad," but after our experience, I think that knowing what is going on and what you can expect is incredibly helpful in figuring out how to address your child's needs better.
Hope you and your family are doing well with this!
