Do I need a monitor with breathing or oxygen tracking?

It depends on your peace-of-mind needs and budget. Owlet's Dream Sock tracks heart rate and oxygen, and Nanit offers sensor-free breathing-band tracking, both popular with anxious first-time parents. However, reviewers note these are wellness devices, not medical monitors, and pediatric guidance generally does not require them for healthy infants. Many parents find a good video-and-audio monitor sufficient.
