I also just want to mention that our cineworld does an autism friendly screening on the first Sunday of every month.
My son absolutely can not sit still, never mind watch a full movie.
We took him to see moana 2, and like clockwork he wanted movement breaks, but we weren't alone at all. Almost everyone's kids wanted movement breaks. Walking up and down the steps or leaving the room, some splash breaks in the bathroom sink, stimming.
I think that was one of the first times I let my shoulders drop because everyone in that room got it.
Now we book as many of those screenings as we can because without opportunity there can't be development, and that applies to more than just the cinema, but the cinema was a designated safe space.
Now, my son is actually excited to go, excited to give the cashiers some money in exchange for snacks and drinks, is excited to print his ticket off at the machines and show it to the ticket collector, and is learning life skills alongside getting out of the house and learning that there are more people who like him deserve to take up space.
I really recommend it if you also live near a cineworld, but don't expect to go and watch a film, just go and expect your child to do what they want and need to do, around others doing the same.
You might only see 20 minutes of film, but the more you do it the more opportunities she will have.
