My son (16) has autism. He struggles with being out of his comfort zone in terms of things like temperature, hunger, tiredness etc. Like as soon as something feels 'wrong' he will obsess about it and make sure everyone else knows (constantly) too. Think - for example - about being in the car for an hour and he's hungry, he will literally complain that he's hungry at regular intervals till you get home even though he knows there's nothing you can do. Obviously we work around it in the ways we can. He never feels cold but often feels too hot. I sometimes go in and he'll have flung open his bedroom windows in January or have a fan on, for example.
He's going on a school trip to the south of France in late June/early July. He really wanted to go and is super excited. We researched and talked about the temperature and talked to the school and explained, but I feel a bit like neither he nor they really understand how unbearable he might find it if he gets hot, especially at night.
Is there anything you can think of that I can do to help? Obviously I'll be far away. When he's here I freeze drinks, give him a cool towl that he can soak and put around his shoulders, he has a fan in his room etc.
