The Fisher-Price Baby-to-Toddler Rocker begins as a relaxing infant rocker or a stationary seat with two bat-at animal buddies perched above. You should then drop the play bar and turn the seat to a toddler rocker as your child ages (up to 18 kg). This rocker is the best (baby) seat in the house, with a deep, comfortable seat, reclining seat back, soothing sounds, and a colourful (and machine-washable) seat pad! Gross motor development: The cute animal friends inspire your baby to reach out and bat, reinforcing those little muscles! Tactile, visual, and auditory senses are all activated by smooth textures, vivid colours, and enjoyable clacking sounds.
