RE: CUTE Long-playing crib Mobiles w/batteries???
Several of my friends have the Tiny Love Symphony mobile. I believe it plays for 15 minutes. Also, several of them have recently had parts on the mobile break (after approx. 7 months of use), but have said that Tiny Love was great about sending out a replacement part right away. (Which leads me to think this is a known problem to them.)
I have a regular CD player (boom box type thing) in the nursery and just keep a stack of classical CDs in her dresser and use those. That way I get 60+ minutes of music. I also use it to help me informally time her naps (this nap went all the way through Vivaldi, but the morning nap didn't quite last all the way through the CD...)
I have one of the "developmental" mobiles (although I guess it is really a stabile since it doesn't move) which she adores. Mine came with multiple cards so that you can add color and pattern complexity at developmentally appropriate times.
