LittleBear did great! He literally didn't fuss once. He loves sitting inside of little cars (like the classic Little Tikes cars, or these carts they have at our mall), so the fact that the kids' chair was a converted Power Wheels jeep interested him from the start. Then he just sat there, through the wetting of his hair (sort of wrinkled up his nose, but he took it) and the cutting (which didn't seem to faze him at all). It went quickly and he was done and ready to move on to the next thing.
(Here's my attempt at a "before and after" comparison. I promise, the difference is much more noticeable in-person.)
Anyways, he did so well! May all his future haircuts go as smoothly... (Oh, and because so many people following him on Twitter have already asked -- here's a photo gallery of the experience.)
Great job LittleBear!
