Our award-winning 100% organic cotton 5-Second Swaddle takes the guesswork out of swaddling with a secure wrap...every time. And because Sleepea was created by world-renowned pediatrician Dr. Harvey Karp, you can trust that every detail was designed with baby safety and parent sanity in mind!

Machine wash in cool or cold water with like colors. Never use hot water or chlorine bleach. Tumble dry on a low heat setting, making sure to dry the sack completely or air dry for best results!

Please Note: Before putting Sleepea in the washer, always attach the arm bands & leg flap to each other and zip the sack completely closed. That will avoid damage that might be caused by the fastener clinging to other items in the load.

Sleepea® 5-Second Baby Swaddle

We lost sleep over creating the best baby swaddle so parents don't have to!

Sleepea is the ultra-soft, simple-to-use swaddle that helps babies sleep longer and happier. Our patented 5-Second Swaddle design makes safely wrapping your lovebug as stress-free as can be!

Because Sleepea is made with soft organic cotton and breathable mesh panels, you can rest assured that your little one will not only sleep comfortably all night long (no matter the season), but they’ll snooze safely, too. After all, Sleepea was designed by renowned pediatrician Dr. Harvey Karp, the world’s leading swaddling expert.

Sleepea’s inner flaps give babies the womb-like embrace they love while keeping even mini escape artists securely wrapped and preventing the wild arm movements and nose whacks that can startle them awake. And, unlike most baby swaddles, Sleepea allows for safe arms-out swaddling, making it the perfect transitional swaddle for babies that are almost ready to wave bye-bye to their swaddling days.

For the first 6 months of life, babies should only sleep on the back. If your baby can roll, you should stop swaddling the arms. That’s because babies need to be able to push up in case they roll to the tummy and the face is pressing against the mattress. (Always consult your baby’s doctor for their advice.)

Please note: To create a continuous groovy design, we made our Tie-Dye Sleepea without mesh panels. (That gives you more of our super-soft, all-seasons 100% organic cotton!) Every Tie-Dye Sleepea is hand-dipped, meaning the designs may vary slightly...making each piece (almost) as unique as your sweet baby!

Swaddling With Sleepea is Easy-Peasy!

Sleepea® 5-Second Baby Swaddle FAQs

What is a baby swaddle sack?
A sleep sack is, essentially, a wearable blanket. And a swaddle is a lightweight square blanket used to wrap an infant. But a swaddle sack is an amazing combination of the two! Here, you get the ease of zip-up sack, plus the cozy hug of a swaddle that infants crave. (Swaddling is an integral part of Dr. Harvey Karp’s 5 S’s for soothing babies.) Our award-winning, pediatrician-designed Sleepea swaddle sack features breathable organic cotton, an easy-peasy two-way zipper, patented escape-proof inner bands…and ingenious shoulder snaps to allow for arms-out snoozing. Unlike other swaddle sacks, Sleepea’s inovative snaps make it so even rolling babies can continue wearing Sleepea! Once babies show signs of rolling, arms-down swaddling must stop. However, if your baby is rolling—and 26 pounds or less—they can remain in Sleepea with BOTH arms out!

Do swaddle sleep sacks work?
Yes! In fact, zipper swaddle sleep sacks work better than traditional swaddles because there’s virtually no room for error…and they’re far easier to use, especially when half-awake at 2am! With the Sleepea 5-Second Swaddle, there are no origami folds, zero intricate tucking, and you don’t need to cross your fingers hoping nothing unravels…which would be super risky. And you can rest assured that you’re not sacrificing quality for ease-of-use. Sleepea’s patented inner bands offer the same sleep-inducing womb-like hug babies have always loved with traditional swaddles.

How do you use an infant swaddle sack?
Sleepea is so easy to use we call it the 5-second swaddle! Simply place your little one on your unzipped Sleepea with their shoulders about two inches above the neckline. Pull one band across Baby’s straightened arm and chest and secure it—and then the other. Then bring the leg flap up between your baby’s legs, attach it to the already-secured arm bands. Finally, zip Sleepea all the way up and get ready for sweet dreams! It’s no wonder Babylist named Sleepea the Best Easy Swaddle!

What are the benefits of sleep swaddles sacks?
Swaddle sacks not only help to activate your little one’s inborn calming reflex, which is their natural “off switch” for fussing and “on switch” for sleep…swaddle sacks are significantly easier to use than a traditional swaddle blanket. With our Sleepea 5-Second swaddle, once you follow the easy-peasy directions, you know that your baby’s swaddle will always be secure, it’ll always be hip-friendly, and it’ll always keep your bub cool and comfy. There’s never a chance of risky unraveling or accidentally wrapping your baby too tight or too loose! Plus, Sleepea takes all of the stress out of trying to unswaddle and re-swaddle during middle-of-the-night diaper changes.

Should I get a baby swaddle with a zip closure?
If you’re looking to take all of the guesswork out of swaddling, then a ready-made baby swaddle with an easy-to-use zipper is for you! While there are several to choose from, the award-winning Sleepea has proven time and again to be a parent and reviewer favorite. (The New York Times, Romper, The Bump, Healthline, and more have all awarded Sleepea top swaddle honors!) Part of the reason: Our ultra-breathable organic cotton Sleepea swaddle features extra-quiet adjustable fastener and a smooth double zipper that help to prevent light sleepers from startling awake. Plus, Sleepea features patented inner arm bands and leg flap, which work together to create a super-safe, secure, escape-resistant swaddle that babies adore.

Why do babies like sleeping swaddle sacks?
Swaddling is an integral part of Dr. Harvey Karp’s 5 S’s for soothing babies. The comforting womb-like embrace of a swaddle helps to activate Baby’s innate calming reflex, which is their built-in “off switch” for crying and “on switch” for sleep. In fact, swaddled babies are able to respond faster to the other four S’s (shushing, swinging, sucking, and holding baby in the side-stomach position)—and stay soothed longer because their arms can’t wriggle around and bonk them in the face!

Is it better to use a sleep swaddle sack with arms in or out?

Choosing to swaddle your little one with their arms in or out depends on how old your baby is. If you’ve got a young baby, arms-in swaddling is a game-changer for quality sleep. The snug arms-in swaddle best replicates the womb experience, helping to activate Baby’s innate calming reflex that quells crying and brings on sleep. That said, some babies start to get ready for arms-out around 3 to 4 months. (Before then, little ones simply don’t have enough motor control over their arms, so they have a tendency to bonk themselves awake a lot.)

If your baby wakes themselves up when their arms are free, they’re just not ready to transition yet…and that is okay! You want to make sure you go at your baby’s pace. The BIG caveat: If your baby is rolling, you must stop arms-in swaddling immediately. However, if your rolling baby is in Sleepea, you can be comfortable continuing to use it as long as your bub has BOTH arms out—and weighs 26 pounds or less.


Is the Sleepea baby swaddle good for transitioning babies with arms in and out?

Yes! Sleepea is uniquely designed to make weaning from the swaddle easy-peasy. That’s because Sleepea features innovative snaps on each shoulder that allow you to gently pull your baby’s arm through for arms-out sleeping. When you’re ready to transition to arms-out swaddling, it’s best to start with the side your baby favors the most. (Once your baby sleeps well for a few nights with one arm free, you can then let their other arm out.)

Remember, once your baby starts trying to roll over, you need to stop swaddling with both arms down right away, just as the American Academy of Pediatrics recommends. However, even a rolling baby can continue sleeping safely in their Sleepea as long as BOTH arms are out and they don't exceed the max weight limit.


How easy is it to use the zipper on the Sleepea baby swaddle?
Sleepea’s smooth-slide two-way zipper opens from top or bottom making it easier than ever to get your bub in and out of their swaddle quickly and effortlessly. In fact, Forbes recently named Sleepea the Best Swaddle For Newborns, noting that our zipper-and-inner-flap design is “built for speed” and a “cinch to put on.”

Is the Sleepea baby swaddle sack breathable to prevent overheating?
Yes! Sleepea’s all-seasons design—complete with 100% breathable organic cotton and mesh panels at Baby’s shoulders and legs—keep little ones cool and comfy all sleep long.

How secure is the Sleepea baby swaddle? And is it easy for my baby to escape?
Our innovative Sleepea swaddle is super secure! In fact, The New York Times writes that Sleepea is “the most effective [swaddle for] keeping a baby securely wrapped,” even awarding our Happiest Baby swaddle top spot as The Best Baby Swaddle. Sleepea’s ingenious inner arm and leg bands offer babies the womb-like embrace they love, all while expertly (and gently) averting swaddle escape attempts—and wild arm movements and nose whacks that can startle little ones awake.

Is the Sleepea baby swaddle made from organic cotton?
Yes! Sleepea is made from 100% GOTS certified organic cotton, making our Happiest Baby swaddle ultra breathable, super-soft, and gentle as can be on Baby’s delicate skin.

The best sleep sack!

My son fell in love with these while sleeping in the Snoo and has continued to love them now that he has graduated from the Snoo. I love that there are internal straps that keep him snug inside the sleep sack, and he loves the gentle pressure of the straps. He has tried other sleep sacks and does not like that he “floats” in them (and frankly, neither do I!). He has space to frog-leg, move around his crib, and get comfortable, but it stays with him. Nothing but great things to report!

Hi Jane,

We love to hear Sleepea is your little one’s favorite swaddle for cozy sleep from day one! Wishing many more snuggly days and nights to your SNOO graduate!

Best,
Sonja from the Happiest Baby Team
