Great find for newborn!

I live these swaddles for my second baby. My first baby needed his hands and arms swaddled in and we had to buy the Velcro swaddles. My second did not do well with the Velcro swaddles at all. He likes his arms up and will not sleep unless he can have his arms up. While nursing I keep his arms out and when he's about to sleep, I stick his hands in so he can still keep his arms up but won't get startled awake. The two way zipper is great for changing, especially those night time changes. I like that the zipper goes to the side versus being just in the front. It makes it much easier for diaper changes. The size worked out great. I bought the smallest size for my newborn and its not overly huge or anything. Fits just right. Definitely worth the purchase and money!

Great product but not what I needed

Why did you pick this product vs others?:This seems like a great product, just not what I needed. I needed something that can keep my baby from escaping AND from touching her face. She for sure can't get out of these but she CAN touch her face so I'll be returning them. They're very soft and breathable and the designs are super cute. The dual zipper is great and very quiet. It was easy to put on her. If your baby is in between sizes definitely size up. I didn't think before buying and got the 0-3 months size when she is 10 weeks, nearly 24 inches and already almost grown out of most of her 0-3 months size clothes. This product would be perfect if it kept her from touching her face. But I'll keep looking elsewhere.

Finally a Swaddle That Works No More Velcro Hassles!

I’ve tried quite a few different swaddles for my baby, and this one has definitely been the most effective. The zipper design makes it so much easier to get the baby in and out compared to the Velcro options I’ve used before (no more noisy rips waking up the baby!).I also love how easy it is to transition—from both hands in, to one hand out, and then to both hands out using the fold-over arms. This has really helped with my baby’s sleep, especially during the tricky transition phases.The fabric is soft, washes well, and has held up nicely even after many washes. I’ve liked it so much that I bought all three sizes to keep up with my baby’s growth so we’ve been able to keep using it as he grows.One small downside: the zipper can get stuck occasionally if I’m not careful, but overall it’s much easier than Velcro.If you’re a parent looking for a safe, convenient, and adaptable swaddle, I’d highly recommend giving this one a try.

Our Little Starfish Sleeps Happy (Even If the Sizing’s Weird)

We’ve officially nicknamed our son the starfish in this sleep sack—and honestly, he’s thriving in it. He’s way more comfortable with his hands up near his face, and this design lets him self-soothe without that “baby burrito” feeling traditional swaddles give.The fabric isn’t anything fancy, but it’s soft, breathable, and hasn’t irritated his skin. It also has a nice amount of stretch, which I really appreciate—when he wants to stretch his legs out, there’s no resistance or restriction, and he stays comfy.The double zippers are a win—middle-of-the-night diaper changes are way less of a production now, and we’ve actually managed to keep him asleep through a few of them (a miracle, frankly).The sizing, though… a bit of a head-scratcher. Our guy outgrew the “small” at around 10–11 lbs, even though it’s supposed to go up to 14.3. The size chart uses shoulder-to-foot measurements, which—let’s be real—is not a measurement most of us know offhand. When we sized up, the arm sections were a little loose and he kept Houdini-ing his hands out. But since he’s just about ready for arms-out sleep, it kind of worked out.It’s held up fine in the wash, the zippers still run smooth, and most importantly—baby sleeps well in it. That’s really all I can ask for.

Very comfy

The material is really light weight, it’s breathable. My son doesn’t like to have his arms in so I just take it out and he sleeps really good with it. When I first got it I didn’t think it would snug him well bc of the material but it’s really nice. It’s also easy to wash and doesn’t shrink in the dryer.

Better than love to dream

LOVE! I only used love to dream or halo for my last baby but they are so expensive for babies that grow so quickly. Took a chance on these and I love them! The material is so soft and I love that the arms can open up without worrying about losing pieces. The zipper function at the bottom is perfect for night time changes. The material is a bit thin so it’d be perfect for summer or early fall babies. We will add layers for our girl in November. I did order a medium and it looks like it’ll fit a 2 week-6 week old unless you have rather large newborns. Very happy with my purchase and I’ll be buying more!

Perfect transition swaddle

Used these when transitioning my little one from a swaddle to a sleep sack. The open slits on the arms made it easy to go back and forth between which arm to keep out.Light weight and soft frantic. Plus much more affordable compared to some other transitional swaddles.

Alright swaddle

Baby does well in these. However, their arms can easily slip through the arm holes. The design doesn’t allow for arms to securely be placed. Love to dream swaddle is so much better, but this is good for in a pinch.
