I have an 8 year old Aspie who chews lots of things.
Generally, and unfortunately, he seems to prefer tiny little pieces of things to chew - lego bits, bits of paper.
He also likes very salty foods and is always snacking on crisps.
They let him have a break in school in the morning but he still chews things constantly. I walked into open afternoon to find him with some staples in his mouth!
We had a meeting with the OT at school with his TAs and we talked about looking for something small, salty, quite hard he could keep in his pocket and chew as he went. The sort of hard bits you might get in bombay mix I suppose.
Any ideas???
