A baby toy spinner is a small, lightweight toy designed to stimulate infants with its spinning motion. It typically features bright colors, easy-to-grasp handles, and smooth edges for safe play. The spinning action engages babies' visual tracking and fine motor skills, often accompanied by gentle rattling or clicking sounds for added sensory appeal. Made from baby-safe materials like BPA-free plastic or soft fabric, it's ideal for tiny hands to hold, twist, and explore.
