Wrapping up our trip to visit Cate a couple weekends ago, here's a video I captured of Cate and Will playing hide-and-seek. Neither of these two is a very good hider - they didn't have a very hard time finding each other. Also in the video you can hear Will trying out his new phrase: "my turn" - which he repeats over and over, whether it really should be his turn or not.
Will is just starting to get this game, and will hide in various places around our house. He especially likes to hide after running away buck-naked when we're trying to get him to take his bath. Also, a big part of hide-and-seek is counting to ten with your eyes shut. We're working on this, Will is getting pretty good at it, but he needs help after about "sic" [six].
