This sensory and bath toy set is a great tool for parents who want to help their infants and toddlers discover numbers, animals, and colors. The spinning gears also encourage fine motor skills, spatial reasoning, and cause-and-effect concepts. Baby will build new creations (and new skills) every time they play with them! Because all 5 colorful gears have suction-cup bases that stick to tile and most other smooth surfaces, they’re perfect for bathtime, floor play, or to toss in the diaper bag and take with you on the go.
