I've posted a few times about my son who is on the waiting list for assessment. He's 7 (I'm autistic too).
I just want advice from those who's kids bolt or refuse to walk.
Today we went to the cinema for the first time since the pandemic as hes CEV. We were the only ones at the showing. He really loved the film and he's been asking to see it for ages but he ended up watching the whole thing with his hands over his ears. He was laughing and at the end said he liked it a lot.
When we got outside, we went for a walk on the beach and I'm now assuming he was still overloaded from the film as he started complaining and was snappy.
When it was time to go he refused to move, literally lay down on the floor. The more we asked him, the more irate he got till he started screaming and hyperventilating and then tried to run away near a busy road. My husband caught him and he started punching his dad and trying to headbut him. He was absolutely hysterical. He had to restrain him in a bear hug till he calmed enough and then he lay down on the floor, as white as a sheet with his head on his dads coat. Everyone was looking, a few people even stood to watch and one asked did we need them to ring for help 
We managed to get him to the bus stop and luckily the bus was already there and he was falling asleep on the bus home.
What's the best way to manage an ASD child who refuses to move or bolts?
I've bought ear defenders in case he struggles like that again with sound. He really loves the cinema and it would be a shame not to take him.
