Knotted Sleepers are made with soft, light-weight buttery softbamboojersey with stretch and comfort. The bottom ties and allows for easy diaper changes in the middle of the night when mama is exhausted. Just untie the bottom knot and pull gown up to change baby's diaper. The Sleeper also comes with mitten cuffs to wrap around your baby's little fingers and a lap-neck style neckline for ease of taking the sleeper on and off. We suggest pulling the knotted sleeper down over their shoulders and body (instead of over the head). From Babysprouts Clothing Company.
