Hi Kath,
It's always a huge shock to get a diagnosis.
I'm on the autism spectrum and I'm dyspraxic. I'm also a mum and have a job I love and friends. There's lots I can't do, but I found plenty of ways round the problems, and help explain what my life is like to others and what can make a difference.
Autism is a different brain design from birth, in which some bits of the brain end up with too much wiring, some with totally excellent amazing wiring, and some with hardly a wire to be seen. A real mixture of good, bad and indifferent.
It doesn't seem to be caused by anything a parent does or doesn't do. They have no clue why some brains end up differently designed to others.
It has advantages and disadvantages, they've found. Generalising, though we can't 'see' people's body language or hear their tone of voice...and we need to know what each day's plans are....and often we have sensory differences....we also have eyesight and hearing that can pick up three times more detail that that of the average person. And we can be ten times more accurate in our work. We also tend to be very persistent, very careful with detail, very honest.
As children we are very eccentric or bloomin' hard work, (until the right sorts of support are in place) and it can seem like it will be that way forever. But 9 out of 10 children on the autism spectrum are able to go on to lead good lives, with the right support and social skills training etc.
There's lots that can be done to help a child with autism. The local autism charities are a very good way to find useful info, good support groups etc. Or look online for the National Autistic Society - their website has loads of useful info and links to services.
Many lovely people here who do fantastic support.
