Just wanted to share that we have been listening to First 5 CA Kids Station on Pandora and really like it! There is a pretty good mix and LO loves dancing to the songs. They are toddler type songs, so if that is not your favorite, this is not the station for you.
PS - I personally also love Party Rock Anthem Radio (although it is unrated and has all the bad words). Two totally opposite stations, but we love 'em!
