This SOOO SOFT MUSLIN SWADDLE is made with 70% Bamboo, which is softer than cotton, and 30% Cotton, which is more durable than Bamboo, for just the right mix of materials. MULTIPLE USES: AS A SWADDLE, the stretchy breathable fabric creates a warm, comforting womb-like experience that contributes to better, longer sleep. Also, by swaddling a baby, one reduces the "startle effect," which wakes or interrupts deep sleep. AS A BURP CLOTH, the blanket protects against stains. AS A PRAM OR STROLLER COVER, the blanket provides sun protection, without overheating. AS A CHANGING PAD COVER, the blanket provides soft warmth between baby's skin and the cooler pad. In addition, the blankets can provide a clean surface on which to change baby. AS A NURSING COVER, the blanket provides privacy for mother and baby. AS A WASH CLOTH, it helps to clean up baby messes. AND MANY OTHER USES, as well. MACHINE WASHABLE. Blankets get softer the more they are washed.
