A ring sling is a type of baby carrier made from a long piece of fabric with two metal or plastic rings sewn into one end. Parents can thread the fabric through the rings to create a secure pouch for carrying their baby. This design allows for easy adjustments to fit the wearer and the child comfortably. Ring slings are versatile and can be used for various carrying positions, such as on the hip or across the chest. They are popular for their simplicity and portability, making them a convenient option for parents on the go.
