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.
