The eyes of the baby are the first doorway to development. With a blurry view at birth a baby can see only a bare minimum. Visual stimulation is very important to develop hand eye coordination and viewing objects in motion helps with 3D recognition. When your baby gets excited seeing the colors and objects in the mobile, it helps in motor development and stirs brain development. We don't believe in making Hippo's and Lion's fly as a small child can't differentiate between reality and imagination. Our mobile elements are things that one would generally find above their head.
