Sam Laughing

This evening, while I was giving Sam a bath he started laugh.  We have had tons of smiles from him, but this was his first true giggle/laugh.  It was one of the best sounds I have ever heard!  I was able to catch a bit of it on camera.  He was, of course, was doing it better before I got the camera out.  The video is a little shaky-I had a 2-year old trying to help me.
