We gave Quinn her birthday present this weekend. It is a ski trainer... what that means is that is is "skis" that have an inflatable peice around it which makes it look more like a jet ski. It has a handle and foot slots so she could stand if she wanted to. We took it to the island and let her ride it... she loved it (she didn't particularly care for the sand / mud at the island though).
She even told Caroline that she (Quinn) would teach her to ski when she was three. :)
