Don't let this cutie-pie deceive you, because it has a powerful agenda—to help baby reach milestones by engaging three important senses. Red, blue and green lights encourage visual tracking. The soft rattle sound awakens baby's hearing, and the textured handle helps little paws get a grip on tactile motor skills. What a power-packed idea, worthy of its many awards! Batteries included. Recommended for infants from birth-12 months old. For nearly the last decade every baby jaZamster has had this toy and ALL have loved it.
