Ring slings baby carriers (called "ring slings" or "baby slings") are one-shoulder baby carriers made of a long piece of fabric attached to a pair of rings. They are easily adjusted and can be worn by multiple caregivers. Ring slings can be used from newborn stage through toddlerhood. For newborns, ring slings work well in the tummy-to-tummy upright position. Ring slings can be used as a front or hip carrier, but also as a back carrier when a child has strong head support.
