Indie's new talent

So yesterday Indie was sitting on the floor and she started bobbing her head back and forth in a way I've never seen before. I thought something was wrong. As the day went on I observed that she did it when she heard music so I realized she was dancing. We thought it was pretty funny, it might just be one of those things that only parents can truly enjoy. She usually sings when she hears music but she's done that for a while. This is all I could get her to do on camera. She usually does it longer. Just ignore my baby voice. It was taken with my phone so it's not very good.
