The ring sling is fast and intuitive to wear on the side, you can use it since your baby is born and it is incredibly comfortable when the baby is about 4 months old to use on the side. It is excellent when breastfeeding and you should always have it in your bag in case of “emergency “. On our website you can choose the right or the left shoulder and this will be the position of the rings. For instance, if you choose a right shoulder sling the rings will be on the right and the baby on the left and vice versa. This does not mean you cannot use a right shoulder sling on the left, but the pattern of the sling will be upside down.
