Because he began to hate them dolfrog. Actually we haven't quite binned them all - he still has SALT once every other week which he loves.
Also I began to feel that many therapists work with the therapy first, child second (Growing Minds I think are probably an exception to that but we can't afford them anymore).
Plus ds1 is 12 now, severely autistic - always will be. Non-verbal - probably always will be although we have high hopes of some pretty good communication with a communication aid (so when I say binned all therapies I really mean binned all autism 'experts' unless they particularly impress me, and then I've found out they're often cheap/free). And I began to feel like we had to get on and live life rather than wait for him to reach some magic ability at which stage we would start doing stuff. He's clearly going to have a severely autistic life so he may as well enjoy it. So now we focus on getting out and about and doing things.
This was in part helped by him falling in love with surfing, so we spend our (somewhat limited after years of autism) money on that now. It's done more for him than a lot of the therapies we spent years on in all sorts of ways. And definitely more for the family as a whole. The people who take him are absolutely brilliant and totally accepting of him.
So this is what he does now:

Of course knowing about reinforcement and understanding the principals we learned during our years of intervention are helpful. And ABA helped him learn to imitate (age 8) which did open a lot of the world to him. But I suppose now I think I know him better than some random expert, and what works with him. He's very very keen to communicate, but can't due to severe language disorder(s) and verbal dyspraxia, but he does a good job of finding other ways and we hope to make that easier for him with a communication aid. Otherwise he just needs to have fun. He's very happy and has an active a busy life with loads of time spent outdoors. That's pretty much what I would like for all my children so we're done with therapies for now. He just surfs every week (and I think he will all winter this year).
