FAQ

Is eufy Baby Smart Sock safe for my baby?
Yes, eufy Baby Smart Sock is safe for daily use with your baby when used as instructed. The sensor tracks your baby's sleep via light reflections (PPG technology) and baby's movements. The sock uses high-quality fabric that wraps comfortably on your baby's feet. All components of the smart sock are carefully selected and manufactured with quality in mind. We have collaborated with parents like you and engaged in rigorous tests to make sure the sock is safe for all.
Will Smart Sock cause a choking hazard to my baby?
Smart Sock is safe for your baby and meets the safety standards. As a precaution, keep the sock sensor away from your baby's mouth.
How many sock sizes are included in the box?
Smart Sock comes in 3 sizes that fit most children up to 18 months old or weigh up to 30 lb. All sizes are symmetrical and can be worn on either foot.
How does Smart Sock track my baby's sleep?
Our sleep algorithm detects the baby's current sleep state based on movements and heart rate. You can use the sock to track daytime naps and nighttime sleep. External activities will affect sleep detection, such as sleeping in a moving stroller, in a car, in a moving bassinet, or being carried in your arms. The sleep detection algorithm best suits a baby sleeping in a bed/crib.
Do I need to pay extra to access video clips or sleep data like other smart baby monitors?
No monthly subscription fee or long-term contract is required. You can access your baby's sleep data, history, and reports at zero cost.

Works great

Glad I purchased this after trying one of the other brands and having trouble connecting it. This works great easy set up, and helps me get some sleep.

GET THIS... Not the Owlet!

This sock is a significant improvement over the Owlet! Every issue the Owlet had has been addressed and enhanced with this design, making it a far superior option.The most significant difference is the ability to customize alerts, allowing you to adjust how they are received, at what volume, and how frequently. Another key improvement is that this product can be used in separate rooms from the base, providing greater flexibility.However, the most notable improvement is the placement of the monitoring probe. This design ensures the sock remains securely in place, making it far more reliable. This addresses a major issue with the Owlet, which often had problems with the sensor shifting out of position.The monitor is great give me the information and peace of mind I needed! Additionally it is easy to apply on my baby and it seems to be comfortable for him to use.Overall, while this product is expensive and not necessarily essential for everyone, it offers long-term value by providing support through various stages of a baby’s development—particularly during times of uncertainty and anxiety. It is a reliable solution that brings peace of mind when parents need to rest and cannot constantly monitor their baby.

BRUE baby

I bought this after my baby stopped breathing at 9 days old and was hospitalized with BRUE episode. Since that time the monitor has alerted me to many incidents of her oxygen dropping at night. We have done many primary care visits along with er and finally pulmonology. Pulmonologist was skeptical of smart socks due to not being “fda approved” and sent an order for hospital grade o2/pulseox machine. Out of curiosity I put both on my daughter (plus smart socks tracks her sleep) numbers have generally been the same (at times smart socks would read 1-2 % higher on o2 and heat rate always exactly the same) would define recommend!

Better than the owlet

Not sure why some people are saying it doesn’t ready blood ox but it does. The sock seems to be a better design with the device sitting on top of the foot, more comfortable for baby. I like that you charge the sock on the base and there is no need for extra chargers or wires.

NICU Baby

I am so glad I purchased this! When I was pregnant I had decided against getting one because people said it created an unnecessary amount of anxiety because they were constantly checking it. However, after going into labor at 32 weeks and my baby spending over a month in the NICU I knew I had to have it for a peace of mind. I didn't know how I was going to survive after always having the monitors to look at while he was in the hospital but this smart sock has exceeded my expectations and allowed me to get sleep knowing my baby is constantly being monitored. If you are apprehensive about buying this, don’t be. You won’t be disappointed!

Great baby sleep monitor

Would recommend this to any new parent. This is the only reason I’ve been able to sleep well as it gives me peace of mind. The app is easy to use.

The perfect gift to put new moms at ease

I wish they had something like this when I had children. Not only can it save your babies life, but it helps. New moms breathe breath of relief, knowing they will be alerted if there’s an issue.

Excellent!

Works just as good as other brands, which I have previously owned and a fraction of the price
