FAQs from the Swaddelini website -
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.
Is the Swaddelini safe for my newborn to sleep in?
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.
What materials and dyes are used to make the Swaddelini?
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.
How tight should the Swaddelini fit my baby?
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
Yes, it can work for babies over 12 lbs. as long as size allows. Make sure their arms are left out once your baby starts showing signs of rolling so they can move freely. The light compression at the chest can still teach them to calm down after experiencing their reflexes.
