It's all very interesting to me. The brain itself is quite interesting how it works and how there really sometimes can be a fine line between a child on the autism spectrum and one that is not. Sometimes it is quite clear and evident...but other times there can be a lot of crossover of characteristics, especially with the PG population. And I can see it would be hard to work on the flapping thing, especially if they don't realize they are doing it. Some things increase when you call attention to it.
