I am sad to report I don’t know anything about Aspergers. I work with a high-functioning autistic kid at my internship and he’s very sweet but also has that personal space thing (he’s still a toddler, so symptoms aren’t super obvious at this point.)
I did have a language gift from a young age much like your kid. By the time I was 10 I literally had reams of half-written novels in my desk drawers, organized by genre. At 11 I started saving up $350 of my own hard-earned cash for a word-processor… not a computer, just an electronic typewriter. Once I finally could afford it (a year later… I’m talking dedication on my part!) I probably spent 6-8 hours daily on that thing up until I left home. I spent recess indoors reading or writing, and it freaked more than a few teachers out. They worried my withdrawal from social activities was a signal of something wrong. But my Mom would reassure them I just really like writing.
I definitely suggest you encourage this gift. For me it wasn’t only something I loved doing, it was something I needed to understand the world around me. I don’t write fiction as well or as often any more, but I still to this day seem incapable of processing events or understanding my own experiences unless I write them down. My whole world is founded on words.
Despite this kind of artistic introversion, I still managed to make friends, succeed, find my way in the world. I may not be the most exciting person on the planet, but I don’t think people perceive me as socially awkward at all. I say that not to minimize the other issues going on with your daughter but to underscore the fact that all kinds of people can fit into a society successfully.
I just can’t help but think that no matter what this child has to face, she is the luckiest kid in the world to have such loving parents who see and celebrate her for who she is. The value of that can’t be stated enough.
