The four position 360 Bundle of Joy Baby Carrier from Ergobaby provides four comfortable and ergonomic ways to carry your baby: on your front facing either you or the world, on your hip and on your back. With its unique, structured bucket seat, padded shoulder straps and wide supportive waistband it will keep your baby comfortable and provide lower back support for you. The soft, Ergobaby Infant Insert cushion (provided) works with any Ergobaby Carrier and must be inserted to support growing babies ranging from newborns to 4-5 months. The design keeps pressure off a baby's developing spine and pelvis. The Infant Insert also provides the necessary head and neck support for comfortable carrying from day one. It snaps around the baby, can be adjusted as needed and placed with ease inside any Ergobaby Carrier. Cosy and protected, your baby will be perfectly cradled and cushioned.
