Does burning off energy help with Anneliese? I know that my friends take their autistic son to the beach regularly in the summer so he can burn off energy in a semi quiet and cool way. He spends an hour or so running up and down the beach in the water and is good to go for a couple of days afterwards.

The beach they go to is close to them, but not as busy as other beaches. They find the lack of other human beings helpful to Etienne as he can just be himself and listen to his own thoughts and nature.
