Ahh another thread!
Alison you have NT children as well. I think there is a hige difference between my autistic child and my NT child. So compare away! My NT child is now 2 and in the middle of tantrums- but they are nothing, I find them quite amusing, he doesn;t hurt himself, they're quickly forgotten - and usually they are over not getting his own way. My autistic child's tantrum are more like meltdowns- he'll lose it completely- and usually it over something being (in his mind) "wrong". He's dropped something, the car's stuck in traffic (so he'll whack his head on the window- hard as he's 5!), we have to queue in the supermarket (no more I don't take him) so he'll headbutt the till.
Ds2 is difficult at times, and for an autistic child ds1 is pretty relaxed BUT ds1 is so much harder than ds2. The 2 can't even be compared really. With an NT child you can reason with them, you can change plans at the minute (eg today as we were about to leave for school ds2 did a poo- so we had to stop to change him and all hell broke loose as ds1 expected to go), you don't have to think ahead all the time with an NT child.
Family etc took a long time to accept my son was autistic. I suspected from 17 months and even after he was dxed at just over 3 people like my MIL wouldn't believe it. After all he looks normal. And he's affectionate which people still can't get their head around. And as he was so passive when younger he was quite easy- content to amuse himself. He looked like a "perfect" child really, smiley, always happy. He seemed to observe everything. Now I see how difficult things like getting his attention was- if I set up a game to play he wasn't interested, if I tried to paint with hi he wasn't interested, if I tried to show him an interesting animal at the zoo he wasn't interested.
We still have problems from family. We visited a zoo on a very busy day- huge queue, ds1 had a meltdwon- anyway I jumped the queue with him (as he's registered disabled we got in free). Then had to try and find the in - laws (who were stuck in the queue). After about 20 minutes (most of it spent screaming) eventually found them and MIL said "oh I thought we would all go and have a nice meal in a restaurant somewhere" WTF? And she wants to know why we haven't got his name down for the local private school (he's non verbal). And she spends the whole time saying "I had 2 children so I know what its like" - except neither of them were autistic and it makes a HUGE difference.
The point being that MIL has seen him growing and she still doesn't "get it", At the zoo visit she took him into a queue to see some lemurs- which has to be the stupidest thing anyone has done. SIL spotted it and said "oh my god what's my mother done" and then the scremaing started. She wanted to walk round the zoo reading every sign at a snail's pace, not realising that if you want to have a day out with an autistic child it HAS to be on their terms or you don't go.
Sorry turned into a rant but just to say that often people who really "should" get it just don't and I realy cannot understand why. I think maybe they just don't want to.
