Product Description

Details

The Swaddelini Bamboo Blend Swaddle Sleepsack - A Safe and Seamless Embrace for Restful Nights.

Introducing the Preemie Warrior Sleep Sack, designed specifically for babies transitioning from the NICU. This innovative swaddle sleeping sack, perfect for little ones weighing 1.8-2.7kg (4-6 pounds), offers a comforting, secure fit that most standard swaddles can't provide. It's an embodiment of love and protection for the smallest warriors.

Crafted with signature 3D-knit technology, the Preemie Warrior Sleep Sack features the patented Hug Technology®. This unique design gently supports your preemie, promoting a calming sleep environment while helping to regulate the Moro reflex, a common concern in premature infants. This product is also undyed.

In the Preemie Warrior Sleep Sack, each peaceful slumber and gentle awakening marks a journey of growth and resilience, enveloping your little one in a comforting embrace of safety and care

FAQs from the Swaddelini website - 


What size does Swaddelini come in and how do I choose the right size?
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

Does the Swaddelini work for older babies that still have strong Moro reflex?
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.
