Hold on to your baby longer with this carrier that adjusts to accommodate newborns up to 3-year-olds. Developed in cooperation with medical specialists, the One Air baby carrier lets you hold your child in an upright position that ensures free air passages, freedom of movement and proper head and neck support. Adjusting to four babywearing positions—newborn, facing in, facing out and at the back—the baby carrier is made of a flexible, breathable fabric that lets you feel your baby's natural body positioning. Not just comfortable for your little one, the carrier in basic black features padded shoulder straps and a wide pressure-relieving waist belt that promotes good carrying positions. Best of all, the mesh carrier adapts to each stage of development. The upper-height adjustment carries infants face-in, while babies five months or older can face outward. At one year, children can be carried on the back.
