I have a friend at work who is a Ukulele freak and loaned me a little soprano uke and an instructional DVD. I've been having fun learning chords and playing silly songs. I though a ukulele might be nice for entertaining Haden, as it's easy to move around, quiet, and high pitched. He seems to really dig it. I've been entertaining him with "Froggie went a Courtin'" and a bunch of other kid songs.
