We attended National Autistic Society parenting courses. It's more of a slightly different way of thinking and parenting.Tips include (and there are hundreds of these):
Don't worry about eye contact, sensory processing issues mean they may not be able to look at you and listen to what your saying at the same time.
Buy the same clothes all the time. Is it really a big deal if he only ever wears white socks? We bought school uniforms a year early and left them in his wardrobe to get used to them. Think Geoff Goldblum in the Fly.
The school let him sit in headmasters office and read an encyclopedia if he was having a playtime meltdown. Did you know slugs have shells?
Allowing and helping him to stim in non conspicuous ways (he spins a pen round his fingers, quite impressive to watch TBH!).
He had a huge collection of soft toys that he took to bed, it got to the stage where the collection got bigger and so did he. There wasn't enough room for all of them so we had to devise a rota!
We got lots of help transitioning from primary to secondary to college to uni.
The big big thing is "choose your battles". Is not being able to dispose of something you have given a name (stoney the stone) a big deal? Not really compared to learning how to cross a road. (This goes for all kids, but doubly for ASC).
The tough times have been tough but the bits in-between have been incredible. The GCSE English grade 5 meant more than all his 9s put together.
