Snug swaddle
This swaddle snugs my baby just right and is Soo easy to use. Love it going to buy two more 😁
Sleep sack
This sleep sack is perfect for my baby! The Velcro straps are wonderful and make for an easy wear. My baby sleeps at least 8 hour stretches since I bought this when he was 6 weeks old!
Exceptional Swaddle
Gave it as a gift — the baby loves being in it — the family loves the calming and soothing effect the swaddle offers. Easy to use and was so appreciated! It’s lovely when a gift is helpful and is loved too! Highly recommend!
Game changer, life saver
This was the last swaddle we ever bought (well, we got a few in different colors) after a long unsuccessful journey of other styles/brands. Our baby monster would hulk out of everything we got and would wake themself up from it every night like clockwork. These swaddles are the easiest to put on, baby loves them, and stays in and asleep more consistently. They’re also easy to clean (I recommend velcro-ing them as if baby were wearing so they don’t stick to other items in the wash) and the 2-way zipper makes diaper changes less of a hassle. 5 stars, will buy again!
Best sleep sack
Hands down the best sleep sack out we have tried. I’ve tried at least 10 different brands, Halo and Love to Dream were my previous favorites, but this one takes the cake. My two-month-old twin girls sleep better every single time they wear these. Easy 10/10. Wouldn’t waste money on anything else
Love love love!!
We are big fans of the SNOO from having our first, and someone accidentally gifted us one of these swaddles thinking it was specifically for the SNOO. We ended up taking it to the hospital — and quickly wished we had brought more. When we had twins a year later, this swaddle was at the top of our hospital packing list. It’s easy to use, works great, and was incredibly helpful during those early newborn days. Now it’s my go-to gift anytime I need a newborn present. Highly recommend!
Quick and easy to use!

This is it!
Buy it! We are getting much more sleep because of it! Thank you Happiest Baby
Our favorite swaddle
We love the Sleepea so much! Very comfortable and easy to use. Helps our baby sleep comfortably.
Current favorite
So far this is our newborn‘s favorite swaddle! She tolerates it well at night and allows us to get a couple hours of Sleep at a time.
Best Swaddle!
This swaddle worked perfectly once our newborn started to get strong enough to fight the muslin blankets! It kept her contained and her startle at bay until she started to roll. She slept through the night easily in these.
Best swaddle
This is the only swaddle you need. We were frustrated with the more traditional Velcro swaddles either coming loose, inching up, or being too tight in the hips. After trying many brands, we found the sleepea and it is all we use now. It’s simply to put on at night after changes, is light and breathable, and most importantly, secure. I don’t go to sleep worrying about my baby pulling this loose.
Our favorite swaddle!
We tried 3 different brands/styles of swaddles for our newborn. This is the only one that he didn’t fight, so we bought several more to rotate through. We used size medium from the start. It’s very easy to use, especially managing it during nighttime feedings!
Saved our sleep
Our baby broke through ever swaddle. This swaddle saved our sleep. Since 5 weeks old she’s been sleeping 9pm - 7am. Don’t event think about it just buy it.
The best swaddle ever!
We tried a whole lot of different swaddles and nothing worked quite as well as this one. Our baby sleeps in it without a peep all night.
I have only used it one night so far so take this with a grain of salt, but WOW! Last night was a struggle getting him to sleep. Waking IMMEDIATELY after putting him in the bassinet. Opened my Sleepea swaddle that had arrived just hadnt bothered to unbox. Washed it and used it. Y’all….my velcro baby slept over 4 hours the first stretch. Usually sleeps 2-3+ hours in the first stretch. He woke to nurse briefly and change diaper, swaddled up again and slept another 2+ hours. Took Dr Karp’s advice also about laying him down when he was sleepy, not asleep. Ordering another swaddle in case this one gets dirty.
Bought 1 to trial for my newborn. As a first time dad, this is one of the best purchases we’ve made so far. Easy to use and my son seems prefer it to other swaddles. Great product. Will be buying more.

Our #1 baby purchase of all time
My husband says “swaddling with receiving blankets is an outdated technology and should be eliminated.”! This swaddle is so much safer than our other swaddle with external wing flaps. We have had six babies and now on our 7th child we finally get to enjoy a superior product. Our baby loves it and it helps baby fall asleep!! Best money I’ve spent this year. Bought 2 more already for a friend. Especially like having a lightweight version for daily use as baby wears warm sleepers all day and we do not want baby to overheat. We own comforter and lightweight versions. NOTE: our baby was in size medium by 9 lbs or so. Still in medium at 12 lbs.
Worked Great for Our 3-4 Month Old!
Had challenges with other swaddles this one did the trick and is still working, he's 4 months now.
This is the best swaddle
We had the Aden and anais swaddles and they sucked. We needed something that would last and was simple. This is it! We keep our room at 65° and use the comforter swaddle for that. The tie dye swaddle is .8 tog and great for warmer rooms. It’s honestly so easy to swaddle. My babe is in a size medium right now and it fits great. She’s growing and will be in a large once 18 pounds. She is able to now get her arms out, at 4 months and 14 pounds. When washing we keep the Velcro together so other things don’t get stuck to it and it dries easier. We wash this every couple weeks unless it gets spit up on it. The price is definitely justified with the ease of it, the fact it stays on and in place, and the longevity. Also they are cute designs!
Snuggly and easy
This swaddle is super easy to use and extremely cozy. Baby sleep great when snuggled up in this swaddle. Also, the sizes seem to run a little small. My baby fit great in a size medium starting around 9 lbs.
A Total Win
We had to stop traditional blanket swaddling when our LO kept squirming out of it around 6 weeks. This was the *only* other swaddle that worked for us—and it really does only take 5-seconds! My only regret is that we didn’t start using it sooner, because he is turning three months soon and we’re going to have to quickly wean him out of it because he’s starting to show signs of rolling. And while he’ll sometimes wiggle his arm out of one side (he’s very determined!), usually if we just tighten up the internal wrap, he will stay nicely bundled all night long. I also do think the weight range is real tight towards the end—he was like a stuffed sausage in a small and was about a pound under the weight limit. Anyway… Just a few things to consider, but overall, we are incredibly happy.
Perfect swaddle!
This is the perfect swaddle! After seeing the halo swaddle bunch up over my baby’s face one night I had to find another solution. This swaddle is just that, no loud Velcro, so easy to use and my baby loves it! I love that it’s breathable and I don’t have to worry about her being too hot like I did with her previous halo swaddles. I wish I had found it sooner and recommend it to all my mom friends! It’s very high quality and holds up well even with daily washes. I bought two more immediately!
Such a big help
So cute and soft and big help with getting baby to get restful sleep.
Best swaddle by far!
Only one my baby couldn’t escape! This is the only swaddle you will need, it is fool proof.
