Air Light Swaddelini Summer Sleep Sack

The Swaddelini comes in small and large sizes. Choose the size based on your baby's weight. The small fits babies 6-12 lbs., but if your baby is born 9 lbs.+, still get the small; the large will be too big. The large fits 12-18 lbs. comfortably.

Yes, the Swaddelini is safe for newborns. It meets and exceeds standards set by world-class, third-party textile safety laboratories. Make sure to leave your baby's arms out once they start showing signs of rolling over.

The original Swaddelini is made from post-consumer recycled nylon. The bamboo Swaddelini is made from 100% bamboo viscose mechanically manufactured and dyed. All materials meet safety standards.

For best results, the Swaddelini should fit snugly with the baby able to move arms to their midline. If too tight, either leave arms out or size up. It uses light compression to help your baby sleep more soundly. If it is too loose, it will not be as effective.
