Swaddle Safe, Sound and Secure Like all Ely's & Co. products, we created our 100% Cotton Muslin Swaddle Blankets with your baby�s safety in mind. We understand the importance of creating a safe sleeping environment, so we designed this lightweight and breathable swaddling choice to help reduce the risk of overheating. The practice of swaddling creates a womb-like feeling of safety, which may soothe a crying infant and lead to a more restorative night�s sleep. Swaddling also helps to promote a deeper and longer sleep by reducing the startle reflex that can wake baby so everyone can sleep peaceful and sound all through the night. 100% Cotton Comfort Guarantee Our Muslin Swaddle Blankets, composed of a single layer of 100% cotton muslin fabric feel gentle on baby�s delicate skin, and are lightweight and breathable for a relaxed comfort. We pre-wash our cotton muslin so you can wrap your little one in a super-soft swaddle blanket from the start.
