I have Asperger's Syndrome, but I did not find out until recently, so as an Asperger's child, I was treated like a normal kid.
Looking back, there were some difficulties and some things were just a little off, but in being treated like any other child, I eventually trained myself to function more successfully in social settings as an adult.
In my opinion, all it takes is just a little more willpower than it might normally take. I prefer to be treated like a typical person, as opposed to being treated as if I have a mental disorder. It is a daily practice, but the older I get, and the more aware of the provisions of my condition become, the easier it gets.
The bottom line is...treat them as you would any other adult.
If you want to get right down to the details though, it helps me a LOT to have a daily schedule/routine. Having a to-do list helps tremendously as well. Finding ways to teach myself how to accomplish certain tasks helps. Focus is a hard one for me, so if my parents ask me to do some things, I have them give me each task one at a time. Telling me all of them at once won't work, because I can't focus that well and I will not remember what they were as soon as I begin the first one. But again, that's where a to-do list comes in handy.
Hope this helps!
