Let's keep every baby safe. Parents around the world trust Owlet every night to help them keep their babies safe while they sleep. Our award-winning Smart Sock goes beyond the capabilities of any other baby monitor to tell you the things that really matter, when it really matters.

The Smart Sock is the first baby monitor to track your baby’s oxygen level and heart rate—the best indication of baby’s health—while they sleep. If your baby’s readings leave preset “safe” zones, you'll receive a notification that lets you know your baby really needs you. Use the sleep history feature to see how long and how well your baby slept and use the data to create new routines as your baby grows. Now you can feel more confidence, more freedom, and more peace of mind knowing that Owlet is here to help you keep your baby safe.  

Our all-new Smart Sock is the third of its kind and it's smarter than ever. 

The Smart Sock also integrates seamlessly with the Owlet Cam. Save £39 when you upgrade to the Monitor Duo.

"We bought the owlet sleep sock monitor for our 5th child. I have always been the parent that checks their baby's breathing 20x a night at the cost of my own much needed sleep. The owlet gives me peace of mind knowing that I will be alerted if there is a dangerous drop in my baby's oxygen level. We are very happy with the product and my son does not seem to mind the monitor at all. Worth the price!"

I’ve recently transferred her into her own room about two weeks ago and having the owlet give me a peace of mind knowing I can Check her heart and oxygen levels and even track her sleep patterns. This is my favourite baby item I have for her!"
