Swaddling recreates the warm, comfortable environment of the womb, which has a calming effect on your baby. It reduces restlessness and improves sleep.
If your baby is restless or cries a lot, swaddling is a tool to help your baby relax and calm down more quickly. In addition, babies are not aware that they have arms. They often wake themselves up, swaddling prevents them from moving their arms, which also provides peace.
