ErgoPouch products are ergonomically designed with a bell-shaped bottom for extra legroom and made from stretchy organic cotton or bamboo to allow babies to move their legs comfortably and adopt the 'frog-leg' position. In fact, our swaddles are perfect for babies who have hip dysplasia as they can be used with legs free if needed, while still keeping the arms comfortably swaddled.
