Jack seems to be on the verge of talking. We got a Christmas card that had dogs in the picture and when Jack saw it he said, "Da! Oof!" (Dog, woof.) And he seems to be saying "ca" a lot for car. But probably the most exciting thing, because it's a very important little boy milestone, is that he can now make a siren sound. And better than that, it's captured on video. Enjoy.
