Lilo sings a lullaby for the new baby

I was a bit shocked by the event captured by this video. Maybe my expectations are too low..
But Lilo sang this lullaby the day she met her new brother. As far as I know, she made this song up on the fly..which is why I am so impressed. It takes her a little time to get going, especially around 1:00 remaining. But it is pretty cool. It may be a bit out of tune, but the fact that it has a consistent structure and a decent melod.
