    5.0 out of 5 stars My baby's favorite!!!
    Reviewed in the United States on November 10, 2024
    My son loves these so much he only sleeps well in these sacks. I've bought 7 so here is the run down:

    Solid colors are a different fabric than the white with print. While both are soft, solid color fabric is softer. Both are a medium thickness. Won't keep them extra warm if the room is cold, if the room is set right the swaddle works perfect.

    Wash with the zipper closed. One of mine got ruined in the wash due to the zipper (devastating loss, we use these every day).

    They are AMAZING for long babies! Not too wide or cumbersome.

    These are not the same as other transitional swaddles. We've tried 4 other brands and he hands down prefers this.

    Lastly, the mintish color, oatmeal darker blue and prints are gorgeous.

    Just throwing in the mix, the muslin blankets are really nice as well!

    Overall if you've read this far, I absolutely recommend these! I know I need more (SwaddleDesigns if you want to send me one please do!!). My 4 month old loves to scratch his face and swing around and these keep him asleep!!

    5.0 out of 5 stars Perfect Transitional Swaddle for a Great Night's Sleep!
    Reviewed in the United States on July 18, 2024
    The SwaddleDesigns Transitional Swaddle Sack with Arms Up Half-Length Sleeves and Mitten Cuffs is a game-changer for my baby’s sleep routine. This swaddle sack has been the perfect solution for transitioning from a traditional swaddle to a sleep sack.

    Comfort and Design:
    The half-length sleeves allow my baby to sleep with her arms up, which she prefers, while still providing a cozy, secure feeling. The mitten cuffs are a fantastic addition, keeping her hands warm and preventing scratches.

    Quality and Material:
    The quality of the material is outstanding—soft, breathable, and gentle on my baby's skin. It's also durable and has held up well through multiple washes, maintaining its shape and softness.

    Ease of Use:
    The design is thoughtful and practical, making it easy to put on and take off. The zipper runs smoothly and the swaddle fits perfectly, allowing for quick diaper changes without disturbing my baby.

    Better Sleep:
    Since using this swaddle sack, my baby sleeps more soundly and for longer stretches. The transition from traditional swaddling has been seamless, and I can see she feels comfortable and secure.

    I highly recommend the SwaddleDesigns Transitional Swaddle Sack to any parent looking for a reliable and high-quality sleep solution for their baby. It has made a significant difference in our nighttime routine, earning it a well-deserved five stars!

    Reviewed in the United States on November 4, 2024
    a great option for babies transitioning out of a full swaddle. The half-length sleeves and mitten cuffs provide comfort and warmth while allowing more movement. It’s soft, easy to use, and helps with sleep, though sizing runs slightly small.

    5.0 out of 5 stars Sleeps just like she’s in a swaddle, but safe for rolling!
    Reviewed in the United States on December 14, 2024
    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.

    I love this transition swaddle! It is so soft and feels like great quality so I know it’s going to last a long long time. This is perfect for my baby who might start rolling any minute now but still needs the comfort of something like a swaddle and I love that his little hands can either be in or out. 100% worth it.

    3.0 out of 5 stars This specific swaddle was just not for my baby.
    Reviewed in the United States on December 9, 2024
    I’m sure other babies might like this, but I personally felt that my baby did not! I don’t think that the arms were long enough to fit an average babies arms! I did like the rest of it though! I also wasn’t quite sure about the arms being in the upward position! But the fabric quality was good! I’d say my baby wasn’t super comfortable in it! It was lightweight though, and the material was the right thickness!

    Reviewed in the United States on December 24, 2024
    Our daughter has been in this since day one out of the womb as her brother hated being swaddled and we brought multiple kinds to the hospital with us in case she did, too. We’ve been using this for about 3 months now and it’s still in great shape—almost like it’s never been washed the 20 some times it has from spit up/drool etc.
    it does get very tight around their torso to their chest, as it’s supposed to, so i was worried about how it would fit as she grew but it’s very true to size and great quality
