Why are so many baby toys in the strong contrasting colors of black and white? This is because a baby's view is still developing before 6 months of age, a stage where they can only see black, white, and gray. Our baby mobile uses strong contrasting colors of black and white, which can help the development of the baby's vision. The five woodland animal patterns can help baby's cognitive development and they can observe different graphic patterns and recognize different animals. The animal patterns are toward the baby's face, not toward the baby at the bottom like other crib mobiles, which helps the baby observe more. The entire Montessori mobile is handmade, using high-quality felt material and polyester fiber filling. It can be used as a wonderful baby shower gift for your dear family and friends.
