Baby A has started making a really funny face repeatedly, most often when he's in his highchair. His eyes will get big and he will tense his jaw and his fists, and even shake a bit, for a split second and then stop. The face is like he is angry, except he isn't. D thinks this is hilarious (and it is kinda funny). So, I thought maybe he was doing it because it makes D laugh, but after he does it laugh, too or anything like kids do when they know they are being funny. All I can figure is maybe he is overcome with excitement for dinner.
