We bought a new mattress this weekend, and our old mattress was leaning on the wall in the other bedroom. Zane started a little peek-a-boo game with Garrett, where Zane would duck under one side as I held Garrett on the other side. I've noticed that we have startled G a few times, which, for some reason, I think is really funny (I'm so mean). The video doesn't show Zane, just Garrett's reaction to him every time he would appear. As you can see, Zane startled him during their little game, but it is worth it, just to here him giggle like that.
