The Octahedron Mobile is the second in the Montessori Visual Mobile Series following the Munari. It consists of three basic colors blue, yellow and red. After baby has perceived basic shapes from the Munari the Octahedron is just perfect to give them an idea of basic colors. We use transparent sticks instead of wooden dowel in order to help babies focus on the colors and shapes. This is how we open the world gradually to a newborn.
