Abstract: A garment for swaddling a baby includes an elongate shell having an outer surface, and an inner surface opposite the outer surface defining an interior volume for receiving the arms, legs, and trunk of a baby therein. The shell has a head end, a foot end opposite the head end, lateral sides extending between the head end and the foot end, and a neck opening at the head end for receiving a neck of the baby. The garment also includes a backboard attached to the elongate shell between the head end and the foot end for preventing the baby from rolling over when the baby is swaddled within the elongate shell. The backboard includes an elongate body for supporting a trunk of the baby. The body has a first face facing the baby when the baby is swaddled within the elongate shell and a second face opposite the first face.
