One of my dearest clients is a six-year-old boy with ASD (Autism Spectrun Disorder or Autism). At times when he is frustrated or confused by the task at hand he may bang his head on the wall, floor or the nearest person.
Last week we had a productive, successful session and I was wrapping up. It was hot and I was wearing white pants with the thought that the light color would make me cooler. While he stood on the rug, I began to clean-up a few things on the floor. I turned, and bent to pick up a puzzle.
It must have been the size of the target and the bright white. Suddenly, while in my precarious position, I received a head butt to my hind quarters that nearly landed me in the second shelf of the bookcase.
If I had been him, I would've done the same thing. It was funnier than anything.
