Thanks for the ideas so far. 
OTE, I'm looking for a link that would give parents of children searching for answers in the neighborhood of autism an idea of 1) normal developmental milestones in both gross and fine motor and 2) possible motor skill issues they might see in their kids.
The site wouldn't need to be specific to autism to be useful though. I have this one which is the best overall I've seen so far but I wanted to see what else is out there.
