The indispensable newborn essential HALO SleepSack Swaddle wearable blanket in luxurious chenille. Coordinating 100% cotton interlock footed coverall and long sleeve bodysuit make this 3 piece set a perfect gift. The HALO SleepSack Swaddle replaces loose blankets in the crib that can cover your baby's face and interfere with breathing. In addition to helping your baby sleep safer, it helps him sleep better, too. Its adjustable swaddle wrap immobilizes your baby's arms to prevent the moro or startle reflex. And, it's the only 2-in-1 adjustable swaddle that allows for swaddling arms in or arms out for baby's comfort and to ensure an easy and gentle transition to the SleepSack wearable blanket when it's time to stop swaddling. Used in hospitals nationwide, the Halo SleepSack Swaddle is the no.1 choice of hospitals, recommended by safety organizations and is approved as Hip Healthy by the International Hip Dysplasia Institute. A portion of every purchase goes to First Candle/SIDS Alliance and The Canadian Foundation for the study of infant deaths. Use over regular sleepwear to take the place of loose blankets. Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle wrap. SleepSack Swaddle is 100% polyester chenille. Coverall and bodysuit are 100% cotton interlock. Size newborn fits 6-12 pounds.
