A swaddle is a soft blanket or cloth used to wrap a baby snugly. This technique helps to mimic the feeling of being in the womb, providing comfort and security. Swaddling can help soothe infants, reduce their startle reflex, and promote better sleep. Swaddles come in various materials, such as cotton or muslin, and can be found in different sizes and designs. Some swaddles have Velcro or zippers for easier use, while others are simple rectangular pieces. Proper swaddling techniques are important to ensure the baby's safety and comfort, preventing overheating and allowing for natural movement.
