This is also true for the rehabilitation professional searching for a specific item for a patient, student, or client. Before going to the expo, talk to your child's therapists. They may already be thinking of specific devices. Ask your therapist if he or she would be interested in attending with you. If you go together, the parent, therapist, and child can work together to evaluate which devices would be most appropriate.
Some people prefer a hand-held tape recorder.
When you arrive, pick up an event program at the door. Carefully review the times of the workshop sessions and the exhibit hall hours. Plan your day's schedule to be sure that you get to see everything you want to see. Don't forget to allow time for bathroom breaks and meals. It's a good idea to spread the workshops through the day.
