Many parents swear by this suit for getting babies to sleep better at night. This transition sleep suit is great for babies who love to be swaddled but are ready to transition. The Magic Sleepsuit has a soft, cotton inner layer with a warm fleece outer layer that provides a comfort geared to promote sleep and soothe. The thick arms and legs help minimize the startle reflex as your baby gets used to sleeping with their arms free, providing longer sleep for parents.
