The Fisher-Price Newborn-to-Toddler Portable Rocker starts out as an infant seat or rocker with a low-profile frame, which is very appropriate for newborns. Then, as your child grows, you can easily convert it to an infant seat to aid interactive toy play, then make it a toddler rocker. It folds easily and has a built-in handle, so it can go wherever you and baby do. The calming vibrations and gentle rocking motion help comfort and soothe baby, while the versatile seat angles add comfort for different age babies. As baby reaches for and plays with overhead and side activities, eye-hand coordination and fine motor skills are being refined. The rattles offer auditory stimulation and the bright colours and patterns stimulate baby’s visual sense. Enjoy years of use with this Fisher-Price Newborn-to-Toddler Portable Rocker, suitable from baby’s birth to weight of about 40 pounds (18 kilograms). The rocker requires one D battery (not included). The seat pad is machine washable.
