SNOO Smart Sleeper Baby Cot FAQs

What is SNOO?

Created by renowned paediatrician Dr. Harvey Karp and MIT-trained engineers, SNOO, quite simply, is a smarter and safer baby bed that can aid a baby’s sleep. SNOO's one-of-a-kind safe swaddling, gentle swaying, and all-night shushing was designed to mimic the soothing sensations of the womb, which activates a baby's innate calming reflex. Plus, SNOO is responsive, meaning it automatically responds to a baby's fussing with the just-right increase of shushing and motion to help calm your sweet pea…often doing so in under a minute. Finally, SNOO has a special swaddle that keeps sleeping babies safely on their backs. Back-sleeping is a top safe-sleep recommendation from all public health authorities, including the NHS and Lullaby Trust. SNOO is so safe, in fact, that over 150 hospitals all over the world place their tiniest patients in SNOO!

Is SNOO worth it?

If safety, peace of mind, and sleep are top priorities for you, then yes, SNOO is worth it! Paediatrician-designed SNOO allows babies to be safely swaddled on their backs—the safest sleep position—for up to six months. At the same time, babies sleep best when given soothing sound and motion. Plus, another study found that SNOO can help parents feel more rested and less likely to feel mentally stressed. Finally, research in the journal PLOS ONE concluded that swaddling, sound, and movement work equally well for soothing babies, whether it comes from SNOO or a loving adult…making SNOO a much-needed helper for parents whose “village” is too far away to offer middle-of-the-night soothing that allows weary parents to rest.

Benefits of SNOO Baby Bassinet

SNOO's womb-like rocking, all-night white noise, and snug embrace of a safe swaddle are specially designed to calm fussing, reduce night waking, and aid sleep. And SNOO's secure swaddle features patented looped “wings” that slide onto SNOO's built-in safety clips, keeping babies from rolling to the stomach during sleep. In short, SNOO:

  • Securely swaddles babies on the back. That means once your precious little one is swaddled in their cozy SNOO Sack and clipped into the bassinet, they will remain safely on their back all sleep long.
  • Triggers the innate calming reflex,which is a baby's “off switch” for fussing.
  • Aids a baby’s sleep with soothing, womb-like sensations.
  • Automatically responds and adjusts to your baby's fussing with motion and sound, often soothing upsets in under a minute.
  • Reduces the need for sleep training. SNOO's weaning mode allows for a gentle transition to cot.
  • SNOO boosts confidence. With the extra help SNOO provides, new parents feel more like themselves, which contributes to overall wellbeing.

SNOO Smart Baby Bassinet Features

SNOO is not your average bassinet. In fact, it is not even your average smart bassinet! SNOO is the only smart bassinet to include all these sleep-aiding and safety features:

  • Safe rocking: Babies love motion (after all, during their 9 months in the womb, they were gently rocked with every movement). However, unlike baby swings that hold babies at an unsafe incline, SNOO provides babies a firm, flat surface as it rocks. Additionally, SNOO's special swaddle is secured to the bassinet so you can rest assured that your bub will remain safely on their back all sleep long.
  • All-night white noise: Research has shown that white noise can help 80% of babies fall asleep in just 5 minutes.
  • Safe swaddling: SNOO's easy 5-Second Swaddle is hip-safe, never unravels, keeps babies safely on the back, and features breathable mesh at the shoulders and legs to keep babies comfy and cool.
  • Easy to customise: Thanks to the free mobile App, you can adjust your bassinet's motion, sound, and fussing sensitivity.

What is a Smart Sleeper?

While the term “smart” is sometimes used for any device that is plugged in or has a connected App, simply being able to move, make noise, or operate remotely does not make a bassinet smart! A “smart” sleeper relies on information from the user (aka your baby) to work more efficiently. SNOO, for instance, is designed to respond to your baby's fussing with a sophisticated algorithm that mimics the actions of an experienced caregiver. That means SNOO automatically chooses the best motion (a gentle rock for sleep, a slightly faster jiggle for fussing babies), as well as the best white noise (soothing rain for a sleeping baby, and louder womb-like sounds for an upset baby) to help calm your little one. Once your baby settles, SNOO reduces its response back to your selected baseline.

How is a Smart Sleeper better than baby rockers?

While baby swings and rockers are fantastic at calming babies—and allowing parents a short break—they are not safe for babies to sleep in. Babies should never be placed on an incline to sleep and never sleep in a swing or baby rocker. That is because a baby's head can flop forward, possibly obstructing their airway, causing suffocation. If left unrestrained, babies can roll over and asphyxiate.

With SNOO, however, your baby is safely rocked while in their own sleep space on a firm, flat surface, which is recommended. It is important to know that not all rocking bassinets are the same. Once your little one starts wiggling and rolling, the motion of a rocking bassinet can make it easier for them to become trapped against one side, which is a suffocation risk. When your baby sleeps in SNOO you can rest assured that they will stay safely on their backs. Back-sleeping is a top safe-sleep recommendation from all public health authorities.

Why choose SNOO over other baby bassinets?

There is no bassinet like SNOO. When compared to other so-called smart bassinets, none of them can keep babies sleeping safely on their backs for all naps and nights. This makes it possible to keep your lovebug safely swaddled for up to 6 months. (When babies are not in SNOO, swaddling must stop once Baby begins to roll.) Plus, SNOO works all night long and automatically responds to a baby's fussing with paediatrician-designed white noise and safe rocking specifically designed to soothe babies back to sleep.

Pros and Cons of Traditional Baby Bassinets vs SNOO

A traditional baby bassinet features a safe, flat, firm sleep surface. And they are compact enough to keep in your room, which is recommended by the NHS for at least your baby's first six months. SNOO features these safe-sleep musts, plus some new ones. For instance, unlike traditional bassinets, SNOO keeps babies securely swaddled on their backs, which is the ideal safe-sleep position for babies. At the same time, SNOO offers babies white noise and gentle rocking all night long—both proven sleep-helpers. And SNOO is designed to automatically respond to fussing with the just-right increase of soothing sounds and motion, expertly lulling them back to sleep.

How to Use SNOO Baby Bassinet
p>It is easy! Once you plug in and set up your smart sleeper, just follow these steps:

Step 1: Swaddle your baby in a SNOO Sack.

  • Open the sack and inner bands and lay your baby down with their shoulders about 5 cm higher than the neckline of the sack.
  • Straighten each arm and snugly pull and secure the inner arm bands across your baby's chest. The bottom edge should cover most of your baby's hands, leaving just their fingers exposed. Next, secure the leg flap.
  • Now, tug the top of the SNOO Sleep Sack up and over each shoulder and fully zip the sack. (The neckline should be well below your child's chin.)

Step 2: Place your baby in SNOO.

  • When you lay your baby in SNOO, make sure their feet are at the end nearest to the Activity Button.
  • SNOO Sacks feature wings with a loop on each side. Slide the SNOO Sack's loops onto SNOO's safety clips on either side of the bassinet. (Do this whether SNOO is on or off.)

Step 3: Turn SNOO on.

  • Press the Activity Button on the front of SNOO. It will blink white for about a minute as SNOO “boots up.” Once it stops blinking, push the button again. This time, the light will turn blue and SNOO will turn on and begin gently rocking and playing white noise.
  • When your baby fusses, SNOO waits a few seconds before responding, allowing them to self-soothe. If fussing continues, SNOO's gentle rocking gets slightly faster and the white noise gets a bit louder. SNOO then moves through four levels of increased sound and motion, until fussing stops. SNOO is designed to “time out,” turn off, and alert parents via the App after a couple minutes of continued fussing, indicating that your baby likely needs a change, a feed, or extra comfort.

Step 4: Customise your SNOO experience.

  • To increase SNOO's level of sound and motion, simply push SNOO's Activity Button for several seconds. As you continue to push, the button will change colour and SNOO will advance to the next level of sound and motion. (You can adjust SNOO's sound and motion with the mobile App, too.)
  • You can reduce SNOO's level of activity with the mobile App. (To stop SNOO, push the activity button once.)
  • SNOO has a special feature called Motion Limiter that allows parents to restrict SNOO's motion to the first two levels (recommended for babies under 1 month). Go to the Settings icon of the App, click on your baby's profile, and toggle Motion Limiter on and save. When Motion Limiter is on, you'll see a M icon in the upper right corner.
  • When Baby is just about ready to move to cot, engage SNOO's Weaning Mode, which plays soothing sound all night—but no motion, unless your baby is upset. To turn on Weaning Mode, go to the Settings icon on the App. Under the Modes category, toggle to Weaning. When the Weaning is on, a W icon will show in the screen's upper right corner.

Game changer - would highly recommend if you want to sleep at night and have quality day naps

Hi Mike,

We're so happy SNOO helps your little one get restful sleep 'round the clock! Thanks for sharing.


Jess from the Happiest Baby Team

Best purchase ever.

Simply remarkable! Could not believe how effective the Snoo is at settling and calming the baby.

Hi Simon,

It means the world to us knowing SNOO is settling your baby's fusses for more sound sleep!

Thanks for sharing & happy SNOOzing,

Jess from the Happiest Baby Team

Great, but not for us

Lovely bed and amazing customer service, but we sent it back after 3 weeks because it just didn’t work for us. Nonetheless I would recommend the SNOO to anyone whose baby likes a swaddle! Our son hated having his arms bound from day one, so I think this is why the SNOO wasn’t right for us. But it’s a great concept. It also looks beautiful (but it’s heavy!), so much nicer than a side sleeper. One other thing to note is that the app notifies you when you need to get the baby, so you can’t really have your phone on silent at night (but I’m sure you could configure notifications from the SNOO app only). Overall a terrific cot but highly specific and not necessarily for every baby.

Hi there,

While we're happy to hear our team made you feel supported, we would've loved to continue working with your family. It can sometimes take a few conversations w/ us to make adjustments to better meet unique needs for the best - safe - sleep with SNOO.

It's true that not every baby loves snug swaddling, so our SNOO sacks have armholes to allow for arms-free sleep. Parents are also able to adjust their device settings to set notifications to alert even if the device is set to silent.

If you have any questions at all, please don't hesitate to contact us at

Hi there,

We couldn't be happier to hear that your entire family is getting the rest you need with SNOO! Soothing your daughter for sound sleep is a dream job.

Hi there,
