Hi, I'm the father of a wonderfully bright, amazing 8 yo who is deaf and uses a combination of ASL and spoken language to communicate. While he learns ASL at an amazing rate, my swiss cheese brain can't keep up with him. He will stump me with signs that I don't recognize, but I desperately want to understand. The attached video is the sign that he used today. If anyone can help me learn what the sign means, I would be very grateful.
