The Fisher-Price Newborn-to-Toddler Play Gym has three ways to play as your baby grows. This convertible play gym takes your baby through the rainforest during tummy time, on an adventure with the hanging pals while they sit, and on a roll with the ball chute during stand & play! With more than 10 activities and toys, and 20 minutes of music and "dancing" lights, this infant gym is wildly fun for your growing little one. Where development comes into play Sensory: Colorful lights and fun music engage your baby's developing visual and auditory senses. Fine Motor: As your baby grasps and interacts with the animal toys and colorful balls, they're strengthening their dexterity and hand-eye coordination. Gross Motor: Those little muscles will get a big workout as your baby pushes up during tummy time, reaches for the toys, and chases after the balls!
