UPDATED on February 17, 2021: We stick to our choices even though we really loved the Wellue BabyO2 monitor. Check our review of this oximeter specifically designed to prevent Sudden Infant Death Syndromes and relies on the same principles as the Owlet sock but for a fraction of the price.

Usually, when we think about sleep trackers, we imagine a fancy smartwatch. This is not always the case. Tracking the sleep of babies is always vitally important. All the new parents will agree!

Baby sleep trackers include numerous high-tech features such as smartphone apps, breathing, movement monitors, and temperature checkers. This abundance of choices can often be overwhelming.

This article will present three different types of baby sleep tracker that we think are the best ones available on the current market. We hope that these products will allow both you and your infants to get back to bed and enjoy relaxing nights.

Why tracking the sleep and movements of your baby matter

To assess the health of a newborn, sleep patterns must be assessed. Being able to provide such information to your baby’s pediatrician is extremely valuable. During the first three months of life, infants will sleep between 13 to 16 hours per day. Baby tech is a great way for parents to understand their babies’ development and lower anxiety associated with babies’ sleep.

Nanit Complete Baby Monitoring System

Best for video monitoring


The Nanit complete baby monitoring system provides everything you will ever need to check your baby’s sleep through the night. To check your little one’s breathing, Nanit doesn’t use an electronic device, but the smart camera will recognize the baby’s breathing wear pattern.

The camera goes on the wall and offers a bird’s-eye view of the entire crib. The picture quality is one of the best on the market and features infrared light for night vision. Three different types of mounts accommodate the HD camera.

The wall mount, which is the default option, the floor stand mount which is self-standing. As an accessory, the company offers an optional Multi-stand mount that can be used when on the go. Picture and sound quality are also simply awesome. The camera also offers real-time monitoring of the temperature and humidity and two-way audio capabilities to always stay in touch with your little one.

The camera connects to your smartphone using the wifi network, which basically offers an unlimited range. As long as the wifi signal is consistent, you will be able to check your little one from everywhere. No matter if your baby sleep on the second floor and you stay in the living room on the first floor, you will always receive a crystal clear picture and crisp sound.

The Nanit sleeping bag works in conjunction with the camera. It detects the printed patterns. The solution is completely sensor free. As your baby breathes, the patterns will move along, and the software will extrapolate the breathing movements. In case the sensor detects a problem, an alert will be displayed both on the camera and your smartphone.

In that sense, the baby sleep tracker incorporates the same technologies you can find in premium smartwatches.

The baby’s oxygen & heart rate are sent remotely via Bluetooth to the iOs or Android associated app. The quality of the sleep, total hours slept, and the number of wakings are also assessed.

The system comprises a camera and a Bluetooth sock that connects to the base via Bluetooth. The base connects to the Wifi network and streams the data to your phone. In case the oxygen level gets out of the “safe” zone, the smart Sock will immediately notify the carer via an alarm on the base and the app.

The sock is wrapped around the foot and secured around the ankle with a Velcro strap. The sensor record the blood flow on the side of the foot. Some parents have somehow reported that the second generation was easier to use than the third one.
