Fisher-Price Infant-to-Toddler Rocker The new Infant to Toddler Rocker from Fisher Price is here! The same great features that moms and babies have loved for years are in an updated frame and fashion! It still grows with baby through the newborn/infant phase as both a rocker and feeding seat with vibration and stimulating toybar. It then becomes a toddler rocker for kids up to 40 lbs. Wonderful new seat pad cradles babies in soft fabrics, then with a clip converts to the more upright seat for toddlers. The Infant to Toddler Rocker is in a fresh new fashion that moms and babies will love!
