ERGObaby's soft, cotton terry swaddler wraps baby in pure, breathable comfort that's ergonomically designed for natural relaxation. The arm pockets cross the body to replicate the in-utero hand-to-heart placement, while baby's hips and legs can move naturally in the frog-leg position as recommended by the International Hip Dysplasia Institute. Since your little one will be sleeping longer and more securely in the Swaddler, it features a removable leg pouch that makes it quick and easy to check and change diapers. Because when baby sleeps, you can, too.
