The Amazing Baby swaddle wrap is 100% cotton and easy to use. The AAP recommends a swaddling for up to 3 months and research has shown that swaddled babies sleep better. Our swaddle wrap includes adjustable swaddle wings that safely secure. We know that moms do not like scratchy Velcro, so our design features soft, premium-quality hook-and-loop fasteners. Set of 2. Small size, fits babies from 7-14 pounds. Machine washable. Designed and ranufactured by SwaddleDesigns exclusively for Amazon.
