The HALO® SleepSack® wearable blanket 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, the HALO SleepSack wearable blanket helps your baby sleep better, too. It is a warm cuddly blanket they cannot kick off; ensuring baby sleeps soundly throughout the night. Use over regular sleepwear to take the place of loose blankets. Size small fits 10-18 lbs. Unzips from the bottom for easy diaper changes. Generous sack design allows room for kicking, but cannot be kicked off so baby stays warm all night. Sleeveless design reduces the risk of overheating. "Back is Best" embroidery reminds caregivers to place baby on his or her back. Choose between pink, blue or green. We embroider any name up to 9 characters.
