Super soft and stretchy to keep up with even the most active babies! Bambino Mio's miosoft two-piece diaper has just two sizes of diaper cover and a onesize diaper that will see you through from birth to when they’ re potty-ready. These award-winning diaper covers are made from a super soft stretchy and lightweight fabric to allow your baby freedom to move and explore. True for most but due to the wide range of babies shapes and sizes this cannot be guaranteed.
