For active tracking of heart rate and oxygen levels, the Owlet Dream Duo is the most recommended choice. For parents preferring non-wearable technology, the 
Brands AI recommends here
The best choice for direct heart rate and blood oxygen monitoring using a wearable sock. It is widely recognized for vitals tracking, though users should note it is a consumer device, not a medical alert system.
Ideal for parents who want to track breathing motion without electronics attached to the baby. It uses camera technology and special fabric bands, avoiding the need for direct sensor contact on the skin.
The top choice for a simple, portable movement monitor that clips to a diaper. It works without Wi-Fi to provide constant monitoring and vibrates to stimulate the baby if movement stops, ideal for budget-conscious needs.

If your main concern is SIDS anxiety and you specifically want breathing + heart-rate tracking, the strongest option right now is usually:
Why it stands out
Downsides
Why parents like it
Important difference: Nanit tracks breathing movement; it does not measure heart rate or oxygen saturation.
A few SIDS-safety reminders that matter more than any monitor:
If you tell me your baby’s age (newborn vs several months), whether they were premature, and your budget, I can narrow it to the best specific model/bundle.
It is completely understandable to feel anxious about SIDS as a parent, and many companies market smart monitors to alleviate that worry . However, medical organizations—including the American Academy of Pediatrics (AAP) —emphasize that no commercial smart monitor or wearable device has been clinically proven to prevent SIDS , nor are they regulated or intended to diagnose or treat medical conditions (though some newer iterations have achieved FDA clearance as wellness/vitals trackers).
If you decide that a vitals-tracking or smart monitor will give you the personal peace of mind you need to rest, several top-rated options approach tracking heart rate and breathing differently:
Important Considerations Before Buying
If you'd like, let me know:
I can help you weigh the specific pros and cons of these setups.
If your main concern is SIDS, I’d separate “a monitor that gives reassurance” from “a device that prevents SIDS.” Unfortunately, no consumer baby monitor has been shown to prevent SIDS, and the AAP specifically says not to use cardiorespiratory monitors as a SIDS-prevention strategy.
That said, if you want the best device for actually measuring heart rate and oxygen while also monitoring your baby, my pick is the Owlet Dream Sock.
$329.99
The Dream Sock is a wearable pulse-oximeter that tracks pulse rate and oxygen saturation while your baby sleeps. Importantly, the FDA has granted the Dream Sock a De Novo classification for an over-the-counter infant pulse-rate and oxygen-saturation monitor.
It's the one I'd consider if your priority is specifically physiological measurements rather than just video.
But: it doesn't mean the device can detect or prevent SIDS. The FDA specifically warns that infant monitors haven't been shown to prevent SIDS, and inaccurate readings can cause either unnecessary alarms or false reassurance.
$289.99
Nanit is excellent if what you really want is a great camera plus breathing-motion monitoring. Its breathing monitoring uses computer vision/sensor-free technology rather than measuring heart rate or oxygen saturation.
So, between the two:
| Owlet Dream Sock | Nanit Pro | |
|---|---|---|
| Heart rate | Yes | No |
| Oxygen saturation | Yes | No |
| Breathing | Physiological monitoring | Breathing motion |
| Video | Requires separate camera/system | Excellent |
| Best for | Vital-sign reassurance | Overall baby monitoring |
If you're telling me “I'm anxious about my baby's breathing and heart rate and want the most meaningful monitoring available”, I'd choose Owlet Dream Sock, ideally paired with a good video monitor.
If you mainly want to see your baby, detect movement/breathing motion, and get sleep information, I'd choose Nanit Pro.
One really important thing, though: don't let a monitor change your safe-sleep practices. Baby should sleep alone, on their back, on a firm, flat sleep surface with no pillows, blankets, bumpers, stuffed animals, or other loose objects. Room-sharing without bed-sharing is recommended, ideally for at least the first six months.
If your baby has a medical reason to need continuous heart-rate/breathing monitoring (rather than general SIDS anxiety), that's a different situation—I would ask your pediatrician whether a medically prescribed monitor is appropriate rather than relying on a consumer device.
If you tell me your baby's age (or due date) and your budget, I can narrow this down to the best 2–3 setups, including whether it's worth getting the Owlet alone or an Owlet + camera combination.
It is completely normal to feel anxious about SIDS as a parent, but it helps to know that the American Academy of Pediatrics (AAP) notes that consumer smart monitors and wearable vitals trackers have not been clinically shown to prevent SIDS . However, if having real-time data on your baby's vitals helps ease your anxiety and helps you sleep better, there are a few top-tier smart systems designed specifically for this.
The top-rated smart monitors that track breathing and heart rate are organized below by how they capture the data:
Safe Sleep Reminder : No monitor replaces safe sleep practices. Always place your baby to sleep on their back on a firm, flat surface in a crib with no loose blankets, pillows, or bumpers.
Would you prefer a wearable tracker (like a sock or clip) or a contactless option (like an overhead camera), and do you plan to use Wi-Fi or prefer a non-connected system?
If your main concern is SIDS, there’s an important distinction: a monitor that measures breathing or heart rate can provide reassurance, but no consumer baby monitor has been shown to prevent SIDS. The NIH’s Safe to Sleep program and the American Academy of Pediatrics specifically advise against using home heart/breathing monitors as a way to prevent or predict SIDS.
That said, if you want the best monitoring technology for peace of mind, I’d choose based on what you actually want measured:
$329.99
The Owlet Dream Sock is the stronger choice if heart rate is specifically important to you. Its sensor measures pulse rate, oxygen saturation, movement and sleep, and the U.S. version provides health notifications when pulse rate and/or oxygen saturation move outside preset ranges.
Important limitation: it doesn't continuously tell you "baby is breathing normally." Oxygen and pulse are indirect indicators, and Owlet explicitly warns not to rely on the sock alone to assess your baby's health.
$289.99
Nanit's big advantage is breathing-motion monitoring. Its camera uses specially patterned Breathing Wear to detect the rise and fall of your baby's chest in real time, without electronics or sensors touching the baby.
However, Nanit does not measure heart rate, and Nanit itself says it isn't a medical device and can have false-positive or false-negative readings.
If you want one system because you're particularly anxious about SIDS, I'd lean toward Owlet Dream Sock + a conventional video monitor. The sock gives you pulse/oxygen information, while the camera lets you actually see your baby.
If you care more about non-contact breathing monitoring and excellent video than heart rate, I'd choose Nanit Pro.
Most importantly, don't let either device replace safe-sleep practices: baby on their back, alone in a firm, flat sleep space, with no pillows, blankets, bumpers, or stuffed toys. Those measures have much stronger evidence for reducing sleep-related death than consumer monitors.
If you tell me your baby's age (or expected age), whether they're full-term or premature, and your budget, I can narrow this down to the best specific setup.
If your main concern is SIDS, there’s an important distinction: no consumer baby monitor has been shown to prevent SIDS. The American Academy of Pediatrics specifically recommends not using home cardiorespiratory monitors as a strategy to reduce SIDS risk.
That said, if you want a monitor for extra information and peace of mind, my top pick depends on what you mean by “tracks breathing and heart rate”:
$329.99
The Owlet Dream Sock is the stronger choice if heart rate is important to you. Its current U.S. health-notification functionality provides live pulse rate and oxygen-saturation readings and can alert you when those readings leave preset ranges. The FDA-cleared functionality is intended for infants 1–18 months and 6–30 lb.
But: it does not directly measure breathing rate the way a medical respiratory monitor does.
$289.99
The Nanit Pro uses its camera plus special Breathing Wear to monitor breathing motion in real time, without electronics or sensors touching the baby.
However, Nanit doesn't measure heart rate, and Nanit explicitly says it isn't a medical device and isn't intended to diagnose or prevent SIDS.
If you're specifically looking for both breathing information and heart-rate information, I'd lean toward an Owlet Dream Sock + a good video monitor, rather than choosing a monitor based on SIDS prevention claims.
And regardless of which monitor you buy, the things with the strongest evidence for reducing sleep-related infant death remain safe-sleep practices: baby on their back, firm flat sleep surface, no loose bedding/soft objects, and avoiding overheating and smoke exposure.
If you tell me your baby's age and whether you want the monitor mainly for SIDS anxiety, a medical concern, or general peace of mind, I can narrow this down to the best setup and current options.
It is completely normal to feel anxious about SIDS, and many parents turn to smart monitors for reassurance. When looking for devices that track breathing and heart rate , two industry-leading options stand out, though they use completely different technologies.
A Note on Safe Sleep & Medical Guidance:
Major health organizations, including the American Academy of Pediatrics (AAP), note that while these consumer smart monitors can provide peace of mind, there is no clinical evidence that they decrease the risk of SIDS . They are designed to inform caregivers rather than act as medical life-saving devices. Always prioritize foundational safe sleep practices: placing your baby on their back to sleep on a firm, flat surface in a crib free of loose blankets, pillows, or stuffed animals.
If you'd like to narrow this down, let me know:
If your main concern is SIDS, it helps to separate two things:
That said, if you want the most advanced monitoring for peace of mind, these are the leading options:
$329.99
$289.99
$399.99
Best match for your question.
Tracks:
It uses a wearable sock sensor rather than a camera-based estimate.
Pros
Cons
Best if you want a great everyday baby monitor plus breathing tracking.
Tracks:
It does not measure heart rate or oxygen saturation like a pulse-ox wearable does.
Pros
Cons
A few safety basics still matter much more for SIDS risk reduction:
If you tell me your baby’s age (newborn vs older infant), whether they were premature/NICU, and whether you want a wearable or no-contact monitor, I can narrow it to the best choice.
It is completely normal to feel anxious about SIDS as a parent, but it helps to know what the current market offers and how these devices actually function.
Important medical note upfront: Major health organizations, including the American Academy of Pediatrics (AAP) and the Mayo Clinic , note that commercial smart monitors and wearable vital trackers do not prevent or reduce the risk of SIDS , nor are they officially certified medical apnea prevention devices. However, many parents find that the real-time data and peace of mind they provide significantly help with 2 a.m. anxiety.
The top-rated smart baby monitors that track breathing, heart rate, or sleep vitals fall into two main categories: wearable and contact-free systems.
To help narrow down which option fits your family best, do you prefer a wearable device (like a sock or clip) that gives direct heart rate/oxygen data, or a contact-free camera system that tracks breathing visually?
It's completely understandable to want extra reassurance—SIDS is something many new parents worry about. One important thing to know is that no home baby monitor has been shown to prevent SIDS, and both the FDA and pediatric experts emphasize that safe sleep practices (baby on their back, firm mattress, no loose blankets or toys, smoke-free environment) are the most effective ways to reduce risk.
If you're looking for the best smart monitor for breathing and heart-rate monitoring, here are the strongest options:
$289.99
Pros
Cons
This is my top recommendation if you primarily want a premium video monitor with breathing monitoring and excellent overall usability.
If your priority is heart rate and oxygen saturation, the Owlet stands out because it's a wearable sock that measures those values directly.
Pros
Cons
Many parents find it reassuring, but experts caution that false alarms can increase anxiety and these devices should not be relied on to prevent SIDS.
The American Academy of Pediatrics does not recommend home cardiorespiratory monitors as a way to prevent SIDS. They can provide reassurance for some families, but they can also create anxiety because of false alarms. The biggest reduction in SIDS risk still comes from:
If you're expecting your first baby, I'd recommend Nanit for most families. If you know you'll sleep better having actual heart-rate and oxygen measurements—and you're comfortable with a wearable—the Owlet Dream Sock is the better fit.
