Oh, I forgot.

He dances now. When I make one of his toys play music, a huge smile comes out and he starts bouncing up and down. He started doing it in the car and I didn't really realize what it was until yesterday when I took out the turtle rattle he has that plays a tune. I pressed the belly and Carson did it. So I've tried on different occasions with different types of music, and sure enough he breaks into dance when he hears the music. Just like his mom. I can't help it!
