When we were trying to figure it out I googled Absence Seizures and found bunches of videos posted of kids having them. I must have looked at 100+ videos and found exactly 2 that looked familiar. One was a little girl dancing in a circle - she never stopped dancing just slowed down for a few beats and then went back to normal speed. The other was a little boy doing his homework who looked up and away for a second or 2. Neither was what I expected to see based on what I had read. You may want to try watching these videos to see if anything looks familiar to you.

Good luck!
