N.B.
You will find alot of info online and from Mamas with kids with AS....I am an Auntie who knew before my In Laws (who are raising the nephew since he was an infant..they wouldnt face up to anything "abnormal"...finally had to when he was older...but I am a child care professional and knew something was up form the time he was about 3...anyways..)
I did a big term paper/case study for college a few years ago on Aspergers, and came across a great book that can help other kids who are around Aspergers (I am an older gal who went back to school, BTW~)... Its called "All cats have aspergers too"
http://www.amazon.com/All-Cats-Have-Asperger-Syndrome/dp/...
Its really a great resource as it can explain for even very young children, some of the issues that AS kids experience, so they can try to understand..like why he yells at her...or doesn't look in her eyes when speaking to her...or talks AT her, instead of engaging in a conversation....or needs things a very specific way (routine and ritual things...my nephew..even at almost 18 eats Chicken fingers/tenders with a bowl of ranch dressing at every single restaurant we go too..pizza place, chinese, burger joint, etc....ALWAYS).....I HIGHLY recommend this inexpensive book!
