I had always just used the music CD that comes with this to calm my 8 month old down at nap/bed time because I don't really like for him to watch TV. He always liked it, but it wasn't anything extraordinary. One day, however, I accidentally put in the DVD (we use a TV/DVD combination to play CDs in his room because we don't have a separate CD player), and my son was immediately entranced. He absolutely loves watching the pictures on the screen, and it has yet to fail to put him to sleep (without any crying or fussing at all). Now, I'm just trying to use it sparingly so the he doesn't get addicted!
