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. US patent, D883,613 with patents in EU, UK, China, Japan, Korea.

Honestly can’t say enough good things about this. He loves being swaddled but was starting to roll. We tried this for the first time at night and it worked so well — he slept straight through! I was skeptical when I saw how much he could still move his arms but those half sleeves are amazing and suppress the startle just enough! It’s super soft fits him well and is way cheaper than some of the other options I saw.

I’m not one to write reviews, never have actually so this is my first one but after a couples months of use I just had to leave my thoughts for those on the fence. My baby was very heavily reliant on swaddling to be able to sleep and had a really aggressive startle reflex so when trying to take it away it was a total nightmare. I decided to give this one a try after failing over and over to get him to sleep without a swaddle. I’m so glad I did cause he loves this transitional swaddle! Been about 3 months of using it and I’ve gotten him back in his own sleep space and taking naps independently again and having longer stretches of sleep (on days/nights I don’t use it cause it’s dirty he doesn’t sleep as long and wakes himself up all night). It’s contoured enough to feel “snug” but still has plenty of leg room and can still put his arms down but helps lessen the arm flailing a lot. Love the double zipper feature and it’s very soft and just thick enough to keep him warm but not overheat. I highly recommend this product for the parents out there struggling to transition out of a traditional swaddle. I got the green one for reference, I read other reviews that said different colors seem to have different fabric and construction and the green one seemed to have the best construction so I went with that one and am definitely gonna get a few more now that I know my baby likes it. Hope this helps

Great sleep sac!! We got the heathered blue for my son and he was so happy and cozy in it. Love the double sided zipper and love that he has space to move his feet. Seems durable, it lasted until he grew out of it. We are very happy with it.

Love this swaddle for my baby who wears this at night since 3.5 months old. Used a medium until 4.5 months. The large one is perfect for my little baby who weighs 15 lbs at 5 months even. It is too long for him at the moment (baby is 26 inches) but I like it because he has room to stretch his legs and arms without coming out of the swaddle. If your baby still needs to be tightly swaddled to sleep, I wouldn’t go with this one at the moment. However, my baby got used to being more free after a couple nights of waking up more often. Breathable, and doesn’t break the bank. Have several since we deal with reflux.

Loved the material and that my daughter can move around but still have herself "wrapped" so she sleeps peacefully. The material is great for all seasons and haven't had any problem with shrinking in the dryer. Only reason for 4 stars is the medium to the large is so drastic see imagaes. But she sleeps perfectly fine. Also love that their is a bottom zipper for diaper changes. Makes it very easy in the middle.of the night.Do keep in mind your child must like to sleep with there arms up (which ours does, so this works great) but may not be for all children.

My 3 month old sleeps best when swaddled but has outgrown all of his swaddle blankets. His legs stick out, he always manages to escape an arm, he gets one or both of his mittens off, and sometimes scratches his face. This solves ALL of those problems! He sleeps so well in this and for a long time. The 2 way zipper makes changing him so much easier and I love that I can keep his hand(s) covered or uncovered. He’s always comfortable in his sleep sack. This is so worth the money. BUY IT!

Update: changed from five stars to three stars because after a week or two one of the cuffs stopped… “working.” Her arm pokes through every time. Like the cuff just rolls away and she gets her arm through. I know that it is some sort of manufacturing issue because it happens every single time, very quickly, on one side, but doesn’t ever happen on the other side. This has been happening for months. It doesn’t matter how I adjust it, it still happens. I think I am going to try to sew it closed, if I can find time. The cuffs are kind of the whole point of this swaddle sleep sack, so if one doesn’t work, it is just kind of a waste of money.My daughter is 6 months old and is still very reliant on a swaddle to sleep. Without a swaddle, she wakes up as soon as I set her down. She also wakes up every time that she starts to rustle, without a swaddle. She can roll from back to stomach in the swaddle, so I have her swaddled just for naps and watch her like a hawk. At night, I don’t keep her swaddled and she sleeps very poorly. I end up bringing her in bed very early in the night. This thing helps her sleep just like a swaddle, and this amazes me! It is definitely safe for a rolling baby, because when she rolls over she can still get up on her elbows just fine.She stays asleep just fine when I set her down in this, and she is able to get back to sleep after rustling around in her sleep. She still isn’t sleeping through the night, but I definitely did not expect her to. She is a breastfed six month old, so it is very normal for her to wake to nurse at night.Note that it is winter and cold in our house, so she is in thick pajamas underneath this, which helps to keep her arms tight and cozy. In the summer, if she was wearing only this, I am not sure whether or not it would have the same effect.Regarding sizing, I found the sizing to be a little odd. I got her the medium, which says 3-6 months and 14-21 pounds. To me, 14-21 pounds seems more like a 6-9 month range. She is six months old and 18 pounds, which is very high in the percentiles. For clothing, she fits best in 6-9 or 9-12 months and doesn’t fit in a single of her 3-6 month clothes, but I still went with the medium 3-6 month size because she fit in the weight range. It fits just fine! It looks a little funny in the picture because she has a jacket on underneath. With the sizing, go with the weight range rather than age. It is also a bit stretchy so I think it will fit for a while.

This is a good transition sleep sack, I tried the bbluv and love to dream before.My baby’s arms and hands can raise higher shoulder level like others.So far, I can see that he can roll over easily in this sleep sack and stretch out during sleep 😄I ordered this size for my 5 months old, it is a bit loose but he seems ok with that, unless your baby like it tighter, hugging feeling, go with his true sizeFabric is soft, no peeling yet and zipper looks great, well-made sleep sack in general
