The SwaddleMe provides the simplest way to swaddle with soft fabric wings that hug your baby close. A leg pouch pops down for quick diaper changes while leaving baby comfortably swaddled. As baby grows, wings adjust for a customized fit. Swaddling soothes infants by recreating the comforting snugness of the womb and new research shows that swaddling may help reduce the risk of SIDS by promoting better sleep when babies are on their backs. Pediatricians recommend swaddling to soothe and comfort newborns, helping them sleep better and also to help reduce colic. A percentage of each SwaddleMe sold is donated to First Candle / SIDS Alliance to help babies survive and thrive. Size large designed for babies 14 to 20 lbs or 26 to 31 inches. Also available in size for 6 to 18 lbs or 19 to 26 inches.
