Seeing those puppets brought me back to when I did in home childcare. Summer time was such a great time for fun dramatic play. One of our favorite things to do was to take a spring tension curtain rod with a curtain on it and put it in the door frame to make a wonderful little puppet stage. We'd make puppets and put on "plays" and retell stories. Why not give it a try with the Polar Bear, Polar Bear Puppets?
