In the Olympia you can begin back carrying at 6 months. When back carrying we want baby to be able to tri-pod sit (baby can sit independently with the support of one of their arms for balance). When baby reaches this milestone, they have developed the torso strength to be able to correct their airway if they slump in the carrier. Since back carrying makes it harder to monitor baby’s airway, this milestone allows baby to help themselves. Although proper monitoring of baby is always an important part of babywearing at any age or stage.
