We’ve tried so many swaddles of various styles for our wiggly baby. She has a strong startle reflex so swaddling was essential for good sleep in her early months. This swaddle is elite! Baby feels snug and secure and those wiggly arms aren’t going anywhere! It stays put and she sleeps soundly. The Velcro is strong. Do note for this style that the entire swaddle must be removed for diaper changes. The double zipper is still handy though if you are putting on and owlet sock for example. If you have a little escape artist, buy this!

Wish I had this with my first baby! Another style of Velcro swaddle were not working, my newborn would easily escape and I was getting anxiety about the top of the wrap near her mouth/ neck. This waddle is amazing, baby is perfectly cocooned, breathable, easy to wash. My 7 week old is now sleeping 5-6 hour stretches. Double zipper is great for midnight diaper changes. My baby is about 10 pounds, and I bought the medium as it is snug.

If there’s a swaddle to get this is the one! We used this for my baby while in the hospital and all the nurses raved about it. It could fit all the wires and easy to change baby without waking. The Velcro works wonders. Definitely safe, just make sure you get the right size or the zipper can push into the neck. I loved the color it’s bright and vibrant and material is thick. I wish I had this one for all my babies! Definitely worth the price.

I work with newborns and this is a easy swaddle to use . I always recommend this for my clients. Specially for new parents this is a great swaddle. I love it because it helps babies to sleep better. Premies babies have a very strong startle reflexes and this helps them stay calm and relaxed. High quality material. The design helps with not being worried that baby will get overheated. I have gifted this swaddle to my many pregnant friends. They loved it. And my clients love them !

I really wanted to love this swaddle, as the quality of the fabric and the stitching is excellent. It’s incredibly lightweight, making it a perfect choice for hot weather. The mesh panels are well-made, and the watermelon print is absolutely adorable. It’s also very easy to use for quick changes. However, there are a few significant issues. First, the sizing is completely off—I highly recommend ordering one size up. I had to return my first one because it was too small, even though I followed the size chart exactly. Second, the design flaw with the middle strap: the piece that is supposed to go between the legs was way too short. At first, I just left it unfastened, but I soon realized it was scratching my baby’s legs and catching on the mesh bottom, which started to damage the fabric. In the end, I simply cut that middle strap off, and now the swaddle is perfect for us! If you are willing to size up and make a small modification, it’s a great product, but it definitely needs better quality control regarding the fit and design.

FIT: My daughter is 4 months old and on the chunkier side. Her chest is about 16" around, when I put her arms into the straps it can barely close and the flap on the bottom is almost a tad too short for my liking, but I think it's just because my daughter is going through a growth spurt. If I strap just her chest and leave the arms on her sides, it's much more comfortable and she doesn't mind. Otherwise, strapped all in is too tight in my opinion. FEATURES: What I like about this swaddle is how secure the velcro is. Once it's on, it's not budging. Even baby Houdini would struggle with it. This is a high quality swaddle. It's lightweight, breathable and worth the value. The material is soft like a cotton blend that has a little puffiness in the fabric. It's like a baby blanket material, but durable. Bonus is the packaging didn't have any annoying tags you had to pop off. It came in a cardboard box packaging. The 2 way zipper is great for times when you need to change the nappy and don't have to undo the restraint. Simply zip upward and change the diaper. A lot of thought was put into the design. My daughter is a little Hulk and my husband had no problems feeding her while swaddled. The arm sections have heavy duty snaps to keep baby's arms inside or you can undo them to have the arms out and contained which works like a sleep sack. Overall: My daughter had no issues adjusting to it. She does not like swaddles, but this one allowing her to have some arm freedom I feel was a good compromise she is willing to make. The only con I can really think of, is if you have a chunkier baby, size up. I think I'll keep mines because I think this would work fine even if her arms are not in the restraints, but in the sack.

i wish i could rate higher!!! fabric is soft but not too soft. thickness is perfect for layering a long sleeve footed onsie or even just a plain tshirt onsie for warmer nights. size is true to size! my girl is an escape artist with swaddles and we had been given one of these in a different style without the diaper fold up and my husband fell head over heels in love with it! enter the diaper fold up style i found! money is well worth it on this one!! color is true to color and patern is even more vibrant in person! pretty sure my husband would give the swaddling on this a 10/10! its THE perfect swaddle for any escape artist in my opinion!

The swaddle is well made and the material feels soft and comfortable. It was easy to use, and I can see why many parents like it. However, it didn’t work as well for my baby as I had hoped, and he was still able to wiggle around quite a bit. Overall, it’s a decent product, but it wasn’t a game changer for us.
