Swaddling is a technique used to wrap a newborn baby snugly in a blanket or cloth. This practice helps to provide a sense of security and comfort, mimicking the feeling of being in the womb. Swaddling can also help reduce the startle reflex, which may disturb a baby's sleep. To swaddle safely, parents should ensure that the baby's hips can move freely and that the blanket is not too tight around the chest. It is important to stop swaddling once the baby shows signs of rolling over, as this can increase the risk of suffocation.
