Just wanted to update...saw the first specialist (child psychiatrist) today. I actually didn't bring up autism, because I was just answering her questions. After having ds2 come in for a little bit, she brought up ASD, and advised me to do some reading on Aspergers. I'm seeing her (alone) again tomorrow, and she's planning to refer ds2 to the clinic I mentioned upthread. She said his behaviour is "quite typical" of kids with Aspergers.
So...not sure how long we'll be waitlisted once I see her tomorrow, but the wheels are turning a lot more quickly than the last time I tried this!
