The Noggin Stik is a great learning toy that looks just like a traditional rattle. We loved that we could immediately start using this from birth for the Alist Baby. It has red, green, and blue lights to stimulate the eyes. A soft rattle noise to please the ears. The handle is easy to grasp and it has a lot of great textures to stimulate the baby’s grasp! I’m sure Kate and Wills will be getting one for their future princess or prince too!
