I wear a Medium and my husband wears a Large. Can we get one size to fit us both?

Unfortunately, sizes don't transfer well. It's like a pair of jeans. You want it to fit just right. If it's too big or too small, it will be uncomfortable and defy its purpose. Fortunately, we've worked extremely hard to make our slings the most affordable on the market for that very purpose. We want Mom and Daddy to be able to get a sling without breaking the bank (then you each get your favorite color, as well!)
