The Transitional Swaddle Sack is the easiest & safest way to wean baby from a traditional swaddle. The arms up sleeve design allows baby to self-soothe and the unique ½-length sleeves with foldover mitten cuffs closed provide partial suppression of the Startle Reflex to promote better sleep. Importantly, the patented design is safer because baby can use their arms if baby rolls over during sleep. The Transitional Swaddle Sack is ideal for babies who prefer to sleep with arms up, babies who are starting to rollover, and babies who break out of a traditional swaddle. The uniquely-shaped, ½-length sleeves are not full length, so when mitten cuffs are closed, baby’s arms will be flexed close to body for swaddle snugness. The foldover mitten cuffs may be worn open or closed. Caregiver can open one or both cuffs, so baby can self-soothe by sucking directly on hand. Helpful 2-way zipper with 2 zipper pulls. The zipper zips down from the top to make it easy to place baby in the sack and zips up from the bottom to make it easy to change baby’s diaper. Designed by a nurse.

So good, I ordered another one!
The Transitional Swaddle Sack has been a game changer for our baby’s sleep routine. The material has the perfect amount of stretchiness, giving our little one enough movement while still providing that snug, comforting feel. Since using it, our infant has been sleeping almost through the entire night, and the improvement in sleep quality has been amazing.The zipper quality is excellent,smooth, durable, and makes nighttime diaper changes quick and hassle-free. It’s incredibly easy to use, even when you’re half-asleep during late-night changes. The fabric is breathable, keeping our baby comfortable without overheating, and soft enough to feel gentle on their skin.Overall, this swaddle sack offers the perfect mix of comfort, flexibility, and convenience. Highly recommended for any parent looking to transition their baby safely and comfortably!

Awesome transitioning swaddle
This was awesome for my son who is transitioning from a traditional swaddle. He slept really well the first time he tried it. Probably a solid 8 hours surprisingly with it being his first time in it. He threw his arms up and slept soundly. He is about 14 lbs and a medium was perfect. He had plenty of room at the bottom to peddle his feet. It is breathable material and feels durable yet soft. And the zipper is smooth.

Absolutely love this swaddle and highly recommend!
My newborn could break out of any swaddle (even the Velcro wrap ones) and loved to have his hands up by his face. As a new mom, I was so anxious about this causing extra loose fabric that could end up over his mouth and nose. I tried a different zip-up arms up swaddle but it didn’t really fit well and it was pretty restrictive and he hated it and would just fight it constantly. Then I found this swaddle and it has been absolutely perfect!! My baby doesn’t fight it and he sleeps well in it. It fits him well, is super easy to put on/take off. I love that the arms can be mittens or open sleeves. The sleeves are perfect where he can sleep with his arms up and there is enough limiting of the Moro reflex, but he can still move and use his arms/hands a little bit. He sleeps well in it and I feel that he is safe and comfortable, so we are both happy!! This swaddle is easy to wash (machine washable and okay to go in the dryer). I like the fabric- it feels soft and sturdy and so far these are holding up great. And the price is very reasonable, in my opinion.

Helped baby to sleep
Worked well for getting our baby to sleep. The material is soft and fit as expected. It doesnt over restrict movement.

Great all around, except for arm length
Love this sleep sack, I ordered a bit larger than needed so he’d be able to grow into it, and that’s worked out really well. Length is good on the body, but the arms are way too short. They come to his elbow, no way I could tuck his hands in if needed. For reference I bought the 9mo size when my baby was about 6mo, just at the minimum weight for that size, and he’s growing into it well. Sleeves have been too short the whole time though, so keep that in mind. Material is a good weight, not too thin not too heavy. He sleeps very happily in it. The double zipper makes nighttime diaper changes a breeze, no waking him up to pull his legs out of footie jammies, thank goodness. The short arms aren’t a deal killer, just a bit annoying.

five star sleep quality
best sleep sack. We stopped swaddling early on and this was the perfect fit for our girl. She doesn’t sleep as well in anything else. We bought multiple to ensure we always have one handy. keeps her warm and cozy and she sleeps through the night!

Perfect Transition Swaddle — Baby Sleeps So Well
I absolutely love this swaddle, and my baby does too! The material is soft, stretchy, and really comfortable no bad smell. We switched to this swaddle when my baby started rolling, and it has been a great transition.I really like the sleeve options — you can keep them closed for babies who still need that snug feeling, or open them once they’re ready. It’s nice knowing we’ll be able to use it for a long time.The double zipper is a lifesaver during nighttime diaper changes. You can unzip from the bottom without taking the whole swaddle off, which makes things so much easier.The color is beautiful, and there are lots of choices.Overall, it’s well-made, easy to use, and helps my baby sleep better. Highly recommend and I will buy more!

Great product, wrong color

Teeny tiny and did not fit. The neck home was made for a doll, try to contact seller but had no luck.

Overall I love the idea of this. This only issue I had was breastfeeding, I couldn’t get her in position to feed, I’d have to take her out of it which defeats the purpose of an easy sack.The material is great, dries fast, soft, warm enough.

Adepte des produits similaires de grande marque, j’ai voulu tester moins cher, affectivement ça fait le boulot en revanche on voit que la qualité n’est pas forcément au rendez-vous, le tissus en coton est bien en revanche la fermeture de qualité moyenne est très épaisse, elle fait des gros bourrelet, et remonte dans le cou de mon bébé je ne suis pas fan de cette gigoteuse, elle est très rigide, j’imagine que c’est normal pour le prix mais sur les autres marques on a des fermetures plus souple donc pas gênante pour l’enfant.Si je dois en racheter une malheureusement je repartirais sur des grandes marques
