It will help you to keep active, and give you freedom.To be sure you're going to fit in this size, measure yourself.Take a long tape measure, or a piece of string, and wrap it loosely around you the way a sling will be worn.Check the length of the tail.^^^^^^^^^^^^^^^^^^^^^^^Just as you'd wash any new garment for yourself or a baby before using it, I would recommend washing your sling when it arrives: in cold water on a gentle cycle. It's not germs that are an issue so much as the sizing and dyeing residues that can remain in the fabric; these will wash out, but until they are washed, the chemicals remain on the fabric.^^^^^^^^^^^^^^^^^^^^^^^Ring Sling are machine washable.To protect the rings, either put a sock over them or put the whole thing in a zippable pillowcase/washer bag. Wash on cold with NO FABRIC SOFTENER, gentle cycle.Lay flat to dry.If you are going to tumble dry, NO DRYER SHEETS and tumble dry as low as possible.Expect some shrinkage.Please, ALWAYS check that your ring sling is in good condition before the first use and after each wash. Do not use a broken ring sling!^^^^^^^^^^^^^^^^^^^^^^^I'm NOT affiliated with Lilly Pulitzer.
