baby rattle

a handheld toy for infants, typically consisting of a handle with a hollow ball or container containing small objects, such as beads, that create rattling sounds when shaken, designed to engage and stimulate babies' senses

A baby rattle is a toy designed for infants that makes noise when shaken. It is usually made from plastic, wood, or soft materials and often has small beads or other objects inside that create a sound when the toy is moved. Baby rattles are typically colorful and lightweight, making them easy for young children to hold and explore. These toys help develop an infant's motor skills, hand-eye coordination, and sensory awareness. They are also used to capture a baby’s attention and encourage them to shake, grip, or move their hands.
