Good but small
Like others have stated the product is small. I got a large and my baby is less than 14 pounds and the large is tight and he won’t be able to wear it too long. The length is ok but wish it was slightly longer. I don’t like how it is very narrow at the waist. It keeps baby secure but seems almost too narrow once zipped. Also, I hadn’t realized that there was an internal seat strap that velcros to the internal straps that wrap around the baby’s arms. I am very confused why the seat strap was designed extremely short. I have to Velcro at the bottom edge of the arm wrap. There really isn’t any stretch so he won’t be able to use it long. May have to cut that part off when he outgrows it soon but it does seem to help deter baby from getting his arms out. However, baby still manages to free an arm from time to time. I wish there was some weight and tightness on the legs because baby still kicks around. Overall, pretty good, but has some design flaws.Update: Baby was sleeping in this swaddle every night. Washed only a handful of times. Tried to wash and dry right side out because others mentioned Velcro wearing out. Unfortunately, that’s not possible. The swaddle has to be dried inside out as well as right side out because the straps don’t dry otherwise. Too wet to hang dry. Takes a long time to dry. After a few months of use, baby now frees his hands all the time because Velro is not as secure and he is stronger at 5 mo. Tried the hands out option but don’t love it. Baby needs gloves and his arms will get cold and moves too much. Switching to swaddle with enclosed arms up seems to be working better now. FYI: Baby does not roll over yet.

Best swaddle I’ve tried.
I’ve gone trough so many different styles of swaddling. This one by far has been the absolute best. We only used the arms and chest velcro because our baby didn’t like the groin one. We simply just folded that part in and it didn’t bother our baby. It’s perfect for night feeding because it’s easy to put on, and it won’t disturb the baby’s sleep much. The only draw back is that you need the correct size, and these are not cheap. However, they are a great investment if it’s the right fit for your baby. I would recommend trying one, and if it works for you then buy the second size up!

Compression Swaddle
Purchased this swaddle for our two month old son who is 14 pounds and 24 inches currently. Bought the 3-6 month size (medium) according to his weight.Pros:-nice and compressive, he likes the secure feeling-fairly easy to use-I like that it can be used when he’s rolling tooCons-pretty snug at his current weight, not sure if it will make it to him being 18 pounds-terrible smell when I opened it, I washed it before he wore it and that helped but the smell gave me a headacheSo far after one night he didn’t get his arms out, but I think he probably could if he really tried to. I’m keeping it as it works great for us now. If you have a very big or long baby it might not be a great fit. Also the fabric is a little stiff, but that’s what makes it compressive, so I guess you can’t have super soft and super secure, you have to pick one!

Used to transition from swaddle to sleep sack
At first my husband and I were wondering if this would be worth it, but after one week we knew it was and purchased two more. The Velcro and zipper are easy to use and the arms button so you can decide if you want your baby to have no, one, or two arms out. The Velcro lasts through many washes and the mesh in the knees prevents our baby from getting hot.

Transitioned from Halo Swaddle to this
My baby has been on the taller side so the Halo Swaddle became too small at 3 months, so I needed a longer swaddle and this Sleepea Swaddle had the best reviews. I would buy this again.Pros:- Seems to be good quality, easy to zip and fabric is soft but thick.-Easy to use, the arm swaddle part is easier to use than the Halo Swaddle- Can use for babies over 26inches long- Breathable, has mesh areas that allow air flow-Baby didn't have any issue with transitioning from halo to this swaddle and continues to sleep through the night.Cons-Cannot put in swaddle before a feed, with the halo swaddle I was able to place baby into the "sleep sack" component. This swaddle I have to wait until baby is fed, burped and asleep. (I was nervous because it means I have to move and adjust baby more)- Seems like the bottom velcro portion is a little shorter than it should be to connect to the middle/arms section

New favorite swaddle
I used to be all about the halo swaddle but this has officially replaced those. I always had such trouble getting baby snug before he’d start wriggling. I found myself wrapping and unwrapping before I got it right, only for him to escape and wake himself overnight.This is sooo easy! It takes seconds to get his arms wrapped PLUS the outer zipper is a double protection from completely escaping. I officially bought a second one.Highly recommend

You NEED this swaddle
This is the easiest and most effective swaddle we have found. It takes seconds to do, it has a two way zipper, it's lightweight and our son sleeps so well in it. It really helps reduce the startle reflex. Just buy it, you won't be disappointed.

Great product
My favorite easy swaddle, but I definitely wouldn't ever buy this in size large as your baby won't like being swaddled long enough to use it. My daughter started breaking out of it like crazy coming up on 3 momths. However prior, it was incredible. I love it for when they're under 3 months ♥️

Great product but…
What I loved: Comes in a large size for large babies. At 4 months my LO was almost 18 lbs and was not ready to be unswaddled. He kept breaking out of his Halo swaddle and I was at my whit’s end trying to keep him swaddled and trying to find a swaddle that was big enough AND not easy to break out of. I was skeptical about this one but once we got it and started to use it, it was like magic! His naps and night sleep became a dream and it was such a relief. The Velcro strap was very strong but also stretchy and soft, and a felt confident that my LO was comfy and cozy. I love the mesh for ventilation as well; I felt confident that he was not going to overheat.What I didn’t like:The Velcro starts to degrade after multiple uses. I guess this is to be expected; hook and loop fabric always starts to lose its hold after extended use. But it seemed to happen fairly quickly. Now it barely attaches. It also ripped at the seams very early on, and while it was still useable, it seemed a bit shoddy. Luckily he’s just about grown out of the swaddle; we use it just for naps now, and only with arms in, not strapped down.So in conclusion, great product, does what it advertises (at least for us), but not great quality for long term use.

Great tool for sleeping, wished it allowed for more growth.
I'm really pleased with the Happiest Baby Sleepea Swaddle. The fact that it's rated America's best baby swaddle and designed by a top pediatrician, Dr. Harvey Karp, gives me confidence in its quality. The use of 100% organic cotton is a big plus, ensuring safety for babies. The 5-second swaddle design and the ability to allow arms out make it a versatile choice. The only reason I'm giving it 4 stars instead of 5 is that I wish it could accommodate more weight as the baby grows quickly through sizes. Overall, a fantastic product that promotes better sleep for both babies and parents.

Good quality.
Our girl is a Houdini. We’ve tried just about every sleep sack and swaddle on the market. I had really high hopes for this product. I’ve read many reviews stating this is the perfect swaddle for escape artist so I thought we had finally found the one. She stayed snug for a couple hours, but as the night progresses, she still managed to find her way out, and eventually woke up from rubbing and scratching her face. We still use this swaddle most nights as it is the one that works the best though.Overall it’s a beautiful product. The fabric is soft and seems like great quality. It is very easy to use. The mesh is nice and makes it very breathable. She doesn’t wake up sweaty anymore when using this swaddle. The Velcro however isn’t as silent as they advertise. So it may startle some babies like it does mine. It’s nice that it has an arm slot option. We open the side slots by the shoulders so that when she does break out she doesn’t get her hands stuck in the neck opening.If your baby isn’t a crazy escape artist like ours is, I believe this could be a really great product and you’d be able to see its full potential. We still love this swaddle and it’s still our go to night time sleeper regardless.

Best sleep sack out there!
We had tried countless sleep sacks for our baby, and this is the only one that has seemed to work!! Since using this sleep sack, our daughter sleeps in 5-6 hour stretches, where as before she was up every 3 hours like clockwork.Definitely recommend!
