When 8-year-old Adam goes to a new place, it can be exciting, almost overwhelming. A visit to a Mexican diner is more than enough to set him off. His head snaps left and right, attempting to take in the scene. His hands begin working, moving up and down excitedly until he is nearly lifting himself off the ground with his “flapping,” as his mother, Heather LeDoux, calls it.

“I have to tell him, ‘No flying at the table,’” LeDoux says. “What I'm trying to do is I'm trying to get him to be aware of how he feels in that moment.”

Adam was born with 10 fingers, 10 toes, and a clean bill of health. But from the moment she took him home, LeDoux — a first-time mother living in her hometown of Questa — was certain something was different.
