Owlet’s Dream Sock is the first FDA-cleared wearable baby monitor. That clearance matters. It means the device’s ability to track pulse rate and oxygen has been reviewed for accuracy and safety, a significant step in the category. This is a health monitor, not just a sleep tracker.

The sock itself is a soft cotton blend that fits infants from 6 to 30 pounds. It streams live pulse and oxygen data to the Owlet Dream App on your phone over a 2.4 GHz Wi-Fi connection. You see real-time readings, sleep trends, and wakings. If readings fall outside a preset zone, you get an alert from both the app and the separate Base Station. The battery lasts about 18 hours, so you’ll charge it roughly once a day.

Setup requires a compatible iOS or Android device. The system provides tangible data for peace of mind, but it’s designed for healthy infants as a monitoring tool. It works best within a consistent Wi-Fi range, and the app is your primary interface for all that detailed information.
