This is a must have if you have small kids. I have four year old twins and they love staying up later then me. When I received this clock I thought it was a good idea but thought it might not work on them. So I gave this clock a try and after using it for a little while they actually caught on to the sleep schedule. If you haven't tried it yet I suggest you do. Whoever came out with this gets a A++++ from me [This review was collected as part of a promotion.]
