Nathan has mastered "Head, Shoulders, Knees, and Toes" at the mere age of 16 months! Ok maybe mastered isn't the term. But he gets the head part, he gets the toes part, and he even gets mouth and nose. He hums along a little bit too. This is why his favorite video is Baby Da Vinci. If you have it, you know what I mean. Lately Nate has taken to spontaneously bursting into the "Head" and "Toe" movements even when we aren't singing.
He also seems to be getting "When You're Happy and You Know It, Clap Your Hands". That is less surprising because he has understood what I want him to do when I say "Clap" for months.
His weekend with the grandmothers and dad must've been good because he hasn't stopped smiling or laughing since I got back.
