It occurred to me yesterday as we were back at Sesame Place (last year's write up) that, as a parent, you can mark time by which rides your kids can go on and the activities they can do.
Yesterday, we did many of the same activities, but a few new ones. And those we repeated, it was clear that the kids had a different perspective.
Just fun to say, "oh, last year they could/couldn't do this and now they are doing that..."
