Welcome to the NeuroTalk Support Groups. I just wanted to let you know also that there is an Autism Forum here as well as this one for Children's Health. Autism Forum
I'm in Australia and my son diagnosed with Asperger's is an adult now. I'd not heard of the doctor you mentioned but just found her blog and have read some of it already. Very interesting. Thanks for that.
Professor Tony Attwood is someone I would call a forward thinker but he specializes in Asperger's Syndrome. http://www.tonyattwood.com.au/
Books -The Autistic Spectrum: A Guide for Parents and Professionals by Lorna Wing
My Social Stories Book by Carol Gray
How to Help Your Autistic Spectrum Child by Jackie Brealy and Beverly Davies
and dozens more.
There is also the OASIS site which I haven't checked out in years, but I just did, and it still has the page for Articles.
There's a list of Useful Websites in the Autism Forum at the very top of the threads. There may be something helpful for you in there are well. Useful Sites - from NT Autism Forum
all the best.
P.S. It's a little difficult to specifically target the age of 3 as you mentioned. Sorry about that.
Many years ago I used to get a lot of my information from a place called the Centre for the Study of Autism.
I see their site is totally changed now, but I'll post one of the papers from there.
