A crib mobile is a decorative accessory designed to hang above a baby's crib. It typically features colorful shapes, animals, or characters that gently rotate or sway, capturing a baby's attention. Crib mobiles are often made from lightweight materials and can be powered by wind-up mechanisms or batteries. In addition to being visually appealing, crib mobiles can also serve developmental purposes. They stimulate a baby's visual and auditory senses, encouraging tracking and focus. Some mobiles even incorporate music or soothing sounds, promoting relaxation and sleep for infants.
