A baby rattle is a toy designed for infants, typically made from plastic, wood, or soft materials. It often features a handle and a hollow body filled with small beads or other objects that create sound when shaken. Baby rattles are used to stimulate a baby's senses, encouraging auditory and tactile exploration. These toys are often brightly colored and may come in various shapes, such as animals or geometric forms. Using a baby rattle can help develop a baby's motor skills as they learn to grasp and shake the toy. Additionally, they can promote visual tracking as babies watch the rattle move.
