A ring sling is a long piece of fabric with a set of two rings on one end. The fabric is fed through the rings to create a pouch for your baby. You can front, hip, or back carry in this type of carrier. I would reserve a back carry for an older infant or toddler. Rings slings are wonderful because they are easily adjustable to for any caregiver to use. It's kind of a one size fits all! These carriers are a great option for quick in and out which is useful for newborns that need frequent changing or for those toddlers that still want to be held. They can provide hands free support from newborn to toddler so it's a carrier that you can use for all of the years you intend to baby wear. Depending on the fabric these can be inexpensive or very expensive. ​ Affordable options: ​ Hip Baby Wrap Ring Sling Luxury options: Sakura Bloom
