Baby mobiles are so much more than just cute objects hanging from the ceiling or crib. Not only can they help soothe and calm your baby, but they are also a terrific way to give your baby's brain a boost. Sensory interaction is important for babies, and that is what's so great about baby mobiles. They are your child's first learning tool, and in time your child will want to reach out and grasp the items on the mobile, thus developing motor and visual skills.
