So all the other kids are standing on the risers with their arms at their sides, and my son is leaning on one leg, then the the other, then he's looking up at the ceiling, then down, then picking imaginary lint off his shirt, then putting his hands in his pockets, then taking them out, etc. etc. etc. I'm very proud of him whenever he stands in front of a packed house for choir, but he's the only one with that degree of fidgets. He's the most fidgety kid I've ever seen. If I had to guess, I'd say it was his sensory issues plus anxiety, but who knows? Just a puzzled little vent.
