Thank you both, I went home for lunch and its hard to watch. He does it a lot. However it looks like its just a tic he started. I think the change of routine, being home for summer, as opposed to very structured days at school. He is normally a little shy, but I would not say a nervous boy. I think staying at home with DW and DS16, are part of it. In a month if thier is no change, we may look at a nurologist, just to be safe. In speaking with my wife we both had some small tics, hers was blinking, and mine was lip licking. But both where minor, I think just because its his eyes, its very noticable.
