It starts out as an infant rocker or stationary seat with two bat-at animal friends overhead. Then, as your child grows, you can easily remove the toy bar and convert the seat to a toddler rocker (up to 40 lbs)! With two comfy recline positions, calming vibrations, and a stylish (and machine-washable) seat pad, you and your little one will love this rockin' seat. Where development comes into play; Sensory: From the rollerball & clacker toys hanging overhead to the calming vibrations in the bright seat below, this rocker can stimulate or soothe baby's senses. Gross Motor: As tiny ones reach and bat-at the overhead toys, they're strengthening those all-important gross motor skills. Security & Happiness: A comfy seat and calming vibrations help soothe babies.
