A swaddle blanket is a type of soft, lightweight cloth that is used to wrap and secure an infant in a snug and comfortable position. The purpose of using a swaddle blanket is to mimic the feeling of being inside the womb, providing comfort and security for the baby while also helping them to feel more relaxed during sleep time. Swaddling can help reduce the risk of Sudden Infant Death Syndrome (SIDS) by preventing the baby from rolling or moving around too much in their sleep. The swaddle blanket is typically made of a lightweight, breathable fabric that allows for proper ventilation and temperature regulation while keeping the baby securely wrapped up.
