Once upon a time I read a little story in a magazine about what "cool parents" do. I can't remember the exact publication now or even when it was released since it was a hand me down. They suggested lots of outlandish things like creating a huge outdoor obstacle course so your children never had to touch the ground!? Not exactly for me but I did come across the idea of the musical tree, so we decided to do it. I just happened to have a huge broken wind chime that was left here when we moved in. It must be fate!
