In addition to helping your baby sleep safer, the SleepSack® swaddle helps baby sleep better, too. Its adjustable swaddle wrap immobilizes baby’s arms to prevent the “Moro” or startle reflex. And, it is the original 3-way adjustable swaddle that adjusts to your baby’s sleep style. Swaddle arms in, one or both arms out to ensure baby’s best sleep and an easy and gentle transition to the SleepSack wearable blanket when it is time to stop swaddling. It’s the easy and safe way to swaddle.
