In addition to helping your baby sleep safer, the SleepSack® Swaddle helps baby sleep better, too. Its adjustable swaddle wrap immobilises baby’s arms to prevent the “Moro” or startle reflex. And, it is the only 3-way adjustable swaddle that adjusts to your baby’s sleep style. Swaddle with arms in, hands-to-face, or with one or both arms out to ensure baby’s best sleep. Adjustable design also makes for an easy and gentle transition to the SleepSack® Sleeping Bag when it is time to stop swaddling. It’s the easy and safe way to swaddle.
