I would really appreciate some experience and advice here as I'm at a loss.
DS2 is just 5. He has delayed and disordered speech and autistic tendencies, although no diagnosis of autism. He is generally quite a laid back kid and I haven't had a huge amount of non-compliant behaviour from him, and when I have its been fairly easy to distract him or calm him down.
Lately however its been getting worse and he gets himself into a complete pickle (over something very small usually) and it seems so hard to get him out of it and I wonder what the best thing to do is.
So for example we went to visit friends at Easter. Arrived at their house and he'd taken his underpants and jeans off in the car as he was hot. I told him he needed to put them back on. He totally kicked off. So I sat in the car with him and calmly repeated myself about 1000 times. The others went in. Now he knows that the friends have lots of toys he likes. He knew there was going to be chocolate. But there was no way he was going to give in and put the jeans on. So I kept persevering and he got more and more distressed. Then I got cross with him and told him he had to stay in the car on his own (I sat outside) which usually he hates. But he just sat in the car and sobbed. We ended up by compromising on just wearing underpants. But that took a whole hour of back and forth between the two of us.
And then an hour later he'll do it again over having to go to bed, or get in bath or whatever.
Now I am trying to prepare for these situations a bit better with visual charts etc. But what I'm really interested in is how you diffuse those hysterical moments. All the tactics I'd use with my NT son don't seem to work and I'm worried I'm just making DS2 worse and more upset.
