Isn't he supposed to be sleeping?

Liam found his vocal chords and he has really been giving them a workout.  I sit by the monitor so that I can hear him in case I need to rescue him while he is sleeping.  But since he discovered his vocal chords I definitely don't need the monitor to be able to hear him.  And lately, he has figured out that he would rather play than sleep anyway. Here is a little video to show you what I mean, but this is nothing compared to when he really gets going! Don't forget, you have the option to watch it full screen in the lower right hand corner.
