Every spring this weird thing happens where the kids come out of hibernation and they've grown about 5 feet taller. Matthew is no exception. He climbs ladders, goes down the slide by himself, yells NO to everything we ask of him (unless the question is "do you want a cookie, Matthew?" and then the answer is Yuh Peeze!), and generally listens when we ask him to do something.
It happens every year, and it always takes me by surprise. Everybody is growing up!
