Another fine motor work! Dh was given this insulated mug at his conference last week, and he planned to give it away since he knew we wouldn't use it. As soon as I saw it, I thought of popsicle sticks. The little opening is the perfect size for a popsicle stick. My mom introduced this work to O while she kept her today. O really enjoyed it and has done it at least 3 times. The most fun is shaking the cup and dancing after she is finished!
