Of all baby monitors we’ve reviewed here at 10BabyGear, breathing monitors are the most essential and perhaps a ‘must-have‘ baby gear every parent should consider. In my research, I came across a wide range of technologies ranging from wearable monitors to high-tech contact-free breathing monitors. My pick for the overall best breathing monitors in 2021 is the Owlet Smart Sock 3 for its accuracy and reliability. As a parent, a newborn can get you tiptoeing into your baby’s nursery just so you can get some ease of mind that your little one is Okay.

Why are they important and what do breathing monitors do?

Breathing monitors can give you back your sleep as you will be able to comfortably monitor your infant’s vital organs such as heart rate, oxygen concentration level, among other vitals.

Unlike adults, babies do not breath at a steady rate and this can worry a lot of parents. Infants have a ‘periodic breathing’ which is breathing with some pausing breathing patterns. This is common for most infants, especially preemies but most parents get distressed by this. You can read more about periodic breathing of newborns here and I am highlighting this to let you know that breaths followed by pauses are normal. Breathing baby monitors are there to enable you to differentiate between normal sleep and breathing patterns and those that may be dangerous for your infant.

SIDs is every parent’s nightmare. 3,500 babies are lost to SIDs in the US every year.

We have put together this piece to assist any parent to reduce the risk of SIDs by taking pro-active steps and by utilizing baby breathing monitors that actually work. At 10BabyGear, we take baby safety seriously and we hope this piece will be helpful to you.

The FDA has never approved any of the baby monitors below as they are not considered medical devices. The National Institute of Health (NIH), and the American Academy of Pediatrics (AAP), recommend against the use of baby monitors for SIDS prevention. They instead advocate for standard practices such as making your baby sleep on the back without being stuffed with blankets and toys. Read more below.

Talking of proactive steps, you can do several things to reduce the risk of SIDs. In the 90s, CDC ran a campaign called “back-to-sleep” campaign and it saw the rate of SIDs drop by half. Before we go into details of these prevention tips, let’s look at some general helpful topics to get us acquainted with the topic.

The idea to monitor the breathing of infants is not new. In fact, the earliest patent for a device that tracks breathing was approved in the 70s by the US Patents Office. In addition, there are great research work and studies around this topic which we’ve reviewed in a period of over 3 weeks to put this article together.

So, what exactly does baby breathing monitor do and is it worth it? Baby breathing monitors are very important and have been known to alert parents in case the baby stops breathing because of an unsafe sleeping position or because of SIDs.

Sudden Infant Death Syndrome(SIDs) is when a baby dies inexplicably and unexpectedly during sleep and it has been attributed to no activity in the part of the brain that controls breathing and heart rate.

When a baby has an inborn problem with the development of that part of the brain, they can die from SIDs when there is a lack of enough oxygen to the brain. For infants with developing brains, they are unable to increase the rate of breathing when there is low oxygen reaching the brain, the way adults would. While SIDs could happen to any baby, there are practices that you can take to reduce the chances of it happening to your baby.

Thousands of parents have found the use of baby breathing monitors to save the lives of babies, proving the point that baby breathing monitors actually work by giving alerts when a baby’s life is at stake. While there is a discussion of whether baby breathing monitors are necessary, I find it very naive to engage in it as studies by CDC and reputable Children’s hospitals have recommended to parents to use a breathing monitor.

It is important to note that while several doctors do not claim that baby breathing monitors can prevent SIDS, they do not deny that it may help by notifying you when there is a potential case of SIDs. Another common question you find is whether baby breathing monitors are safe. Baby breathing monitors are safe as they emit very low emf radiation compared to video baby monitors and are less prone to hacking.

How Baby Breathing Monitors Work:

Principally, baby breathing monitors are meant to track your baby’s breathing and several of them give you various vital signs including the heart rate, oxygen level and breathing rate per minute(bpm).

Different baby breathing monitors use different technologies such as pulse oximetry, computer vision, movement tracking technology, and respiratory motion tracker, among others. 

All these different technologies essentially aim to get the breathing patterns of your baby and some give you the exact breathing levels while others only alert you when the baby stops breathing for a certain period of time. Either way, they all alert parents when the baby is at risk of low oxygen supply and possibly death.  

How to choose the best breathing monitor:

  1. Vitals: Depending on the vital signs you want to track, get the breathing monitor that tracks that vital sign
  2. Style & function: Several breathing monitors have different types of tracking your baby’s vital signs. For example, some have a clip version that attaches to your baby’s clothing while others are entirely non-wearable. In addition, some need to be positioned below the mattress.
  3. Audios and videos: Breathing detection is a special feature but you can pick monitors that have audios and videos as well.
  4. Portability

6 Best Breathing Monitors 2021

Best Baby Breathing Monitor 2021: Owlet Smart Sock 3

Until 2015, there wasn’t a truly reliable baby breathing monitor that tracks key vital signs such as heartbeat and breathing rate of infants. Since the release of Owlet Smart Sock, it has remained the favorite for most parents that have continued to rely on it.

In 2021, our overall best breathing monittor is owlet’s 3rd generation smart sock which was released in July 2020.

Best Baby Breathing Monitors Reviews

1. Owlet Care Smart Sock 3: Anklet/Sock

Owlet Smart Sock 3 emerged as the overall best breathing baby monitor that uses a unique technology that was discovered in the 1940s. The pulse-oximetry technology was locked up in hospitals for decades.

Owlet is a baby breathing monitor anklet/sock that uses pulse oximetry, a technology that uses LED light to get critical vital signs details, specifically the oxygen level and the baby’s heart rate.

Owlet smart sock 2 has been available in the market since July 2017 but the complete Owlet smart sock with a camera has been available since February 2019. Owlet Smart Sock 2 made it to our list of best baby breathing monitors for the second year in a row mainly because of the following three reasons:

  • Pioneering and most accurate readings of the baby’s breathing using a smart sock that has since been improved from the first generation, smart sock 1, which was released in 2016. The technology was first tried out in 2010 and went through rigorous testing that enabled it to be a dependable baby breathing monitor sock. Pulse oximetry, as a technology that obtains details on the breathing rate per minute and the oxygen levels in the blood, has been around for more than 3 decades but Owlet pioneered a home-use pulse oximetry device that is changing the lives of many parents. This point went a long way to our ranking of Owlet as the best baby monitor to monitor breathing in 2019.
  • Easy to use Owlet app which has all the details about the baby’s breathing and oxygen levels with just one swipe up. The app is also free although you’d have to pay to use another version of the app called Connected App that is currently available only on iOS devices.
  • Multiple alerts: Owlet smart sock has been designed to alert you by changing the color of the base station from green to red or yellow in case your attention is needed and those alerts can also be sent to your smartphone. This makes it very easy for you to be updated anytime when your baby needs you.

When you purchase Owlet Smart Sock 2, it comes with the following:

  • 3 washable socks that comfortably wrap around the baby’s foot and connect to a base station up to 100 ft. away using. The socks are ideal for infants of 0-18 months.
  • The base station which receives information from the sock
  • The smartphone App that receives the information on the base station

Before Owlet Smart Sock 2 was developed by Owlet, a start-up that had to pivot a number of times before its great success, parents had to depend on breathing monitors with clips. The clips had to be attached to the diapers or to the chest of the baby and this was some real work. Owlet made it very simple and easy to monitor the baby’s breathing using a technology that has been used for decades in hospitals.

How Owlet works:

Owlet smart sock allows you to track the baby’s heart rate and oxygen levels when asleep. It uses clinically-proven pulse oximetry, and as a parent, you’ll be alerted if the breathing patterns are out of the ordinary. The Owlet smart sock 2 has a base station that glows green when everything is working as expected. Sound and light notifications are sent to your smartphone in case you are needed.

  • Tracks: Heartbeat and oxygen levels
  • Notification: Light, sound and smartphone app
  • Apps: iOS and Android Apps


  • The monitor gives parents peace of mind and quality sleep knowing they will be alerted anytime the baby’s heart rate and oxygen levels are out of the preset range

Unlike Owlet which uses a smart sock to keep track of the baby’s heart rate, Angelcare AC517 uses a sensor pad that is placed at the bottom of the mattress. This means that no gadget comes in contact with the baby. It is Prime eligible if you purchase it on Amazon. It is significantly cheaper than Owlet, coming at almost half the price.
