My son who is five and one of my daughter's who is almost four both listen to this CD every night. It is an integral part of our night-time routine. In fact, when we vacation, we even take a portable CD player with us, just so that they can hear their "Barney Sleepy-time" CD. The music is typically, sweet Barney-ish music and there is kind of a rhythm to the pace in that the beginning of the CD is a little peppier and the second half is definitely more mellow and sub-dued. I have tried to suggest to my five year old that maybe he would enjoy some other type of night-time CD---but no go--at least for now, this Barney CD with its sweet, peaceful tone is what he wants. Our two year old is ready for her big girl bed--so it's almost time to order her CD, too.
