We had twin baby girls and one twin had a complete heart block. This required open-heart surgery at 3 days old and she now has a pacemaker. She got to come home 6 weeks later and being able to use the Owlet Smart Sock has given us such peace with our girls. Knowing both of their heart rates and oxygen levels and being able to track them in the app has been so reassuring for our heart warrior and her twin. We are so thankful for these.
