Well, I am POSITIVE I am AS. I, like some others(that WERE diagnosed AS), started talking VERY early. My mother said I was talking in 100% understandable SENTENCES by about 10 MONTHS! I went to the hospital when I was about 18 months old, and my mother said I was even chatting with the nurses.
BTW I WAS shy, but I was VERY curious. I spoke to various adults all the time. I STILL will if they are respected by others, unique, intelligent, or know something I don't.
Asperger DID talk about little kids talking like adults, so it FIGURES that some started speaking very early.
BTW the normal milestones are saying simple words at 6 months, and 50% understandable sentences by 2 years.
It is a pity I didn't learn other languages so fast. Then again, I DO notice that I become a LOT more fluent in other languages after getting immersed in them for even a few minutes!
I admit that 10 months sounds early, but some said they started talking even earlier. even 2 years with no point of reference sounds fast. Somehow, however, almost everyone seems to pick it up to at least SOME degree. Even people that can do little else. Even the "non verbal" ones here are often so good that you wouldn't know they hardly, or perhaps never, talk.
