From soothing to playing and eating, the Fisher-Price Newborn to Toddler Portable Rocker keeps babies cozy and secure … even as they grow! It starts out as a stationary infant seat or rocker and has an overhead toy bar for bat-at fun. For soothing, try adding the calming vibrations. Then, as your child grows, you can easily remove the toy bar and convert the seat to a toddler rocking chair! Best of all, it folds flat for convenient storage and travel. Where development comes into play Gross Motor: As your baby reaches for and bats at the overhead toys, they’re strengthening those all-important gross motor skills.
