When my David was first diagnosed, the word "autism" was a terrifying thing. It was enormous. Huge. This incredibly astronomical obstacle that was keeping my child from being who he really was. It must be cured! He must not be autistic as soon as possible!!
Right. Good luck with that.
The truth is, there is no "cure" for autism (and that's fine - I love my kid as he is), but there are "work-arounds" for autism-related behaviors. A good friend who works with children on the spectrum once explained it to me like this: remember dyslexia? Nobody talks about it much anymore, but fifty years ago, many dyslexic children were thought to be cognitively impaired, impossible to teach, or "problem" kids.
Then people began learning about how dyslexia works, and what dyslexic people are experiencing, and teachers began teaching children with dyslexia in ways that they could process and finding pathways around and over common obstacles to people who experience dyslexia. Now it's just not a big deal when someone says "Oh, my kid is dyslexic." It's probably not any more common than it used to be - we just understand it better and know how to work with it now.
My hope is that someday, maybe ten or twenty years down the road, someone will say "My child is autistic" and it'll be no big deal. Teachers and employers know how to work with it, and children on the spectrum will have the benefit of learning all the ways to "work-around" the common stumbling blocks they face.
They'll know which scripts to pull out in a social situation. They'll know to take two steps back so they're not standing too close when they talk. They'll know to break their focus when they're ignoring or not engaging properly. They'll be able to mirror people and show the empathy that they all have (and don't ever let anyone tell you they don't!) and just be an active participant in their own life and the lives of others.
Until then, I'll just keep helping David find his own 'work-arounds', and we'll wait for the rest of the world to catch up.
