The Best

We recently went from the swaddle sleep sack to the arms out. It has been a great transition. Our sweet girl is still sleeping through the night with no issues and loves the comfort of her new sleep sack.

That’s wonderful to hear—thank you for sharing! ❤️ We’re so glad the transition to Arms Out has been smooth and that your sweet girl is still sleeping soundly. It’s amazing how comfort and good sleep can go hand in hand!

Good Service

I haven't used the item. It is a present for my son and his wife who are expecting my first grandson. I think they will be delighted.

I wish it worked for us

I was underwhelmed with the quality of fabric for this product, it was very rough and was not very stretchy as it appears online. Unfortunately my baby did not like the product either as he likes to sleep with this knees bent and spread wide. The compression of the fabric bottom did not allow his knees to spread and reach the ground as perhaps it was too small for him despite ordering the larger size. He is 3 months, 15 pounds. I love the idea of this product but it was not for our family. I wish I could have returned it after trying it on my baby as it was quite expensive.

FAQ

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.
