Baby swing stroller Two different modes: It can be used as early as 10 months of age as a Rocker, and also later as a Roller, by adding 360° castor wheels to the base. Rocker Mode: Swinging back and forth, toddlers can learn balance and strengthen their core. The precise design prevents any risks such as tipping over. Roller Mode: The friendly steering allows kids to roam around the house, propelling themselves intuitively with their feet, and the 360-degree caster wheels allow for movements in any direction, building balance and coordination. DESIGNED FOR SAFETY: Keep your little ones safe with our subtle design, extra grip texture, and soft plush.
