The owlet smart sock 2 has really opened my eyes as to how my baby sleeps. It’s amazing being able to see your baby’s heart rate and oxygen levels changing as she sleeps. This is an ingenious invention although I fear it could turn me into an obsessive phone checker as it’s amazing to be able to see these things in the palm of my hand. I used to love listening in on my baby’s heartbeat during my wife’s pregnancy and now I can see it all the more right in front of me in my hand. I’d totally recommend people give this ingenious invention a try for themselves as it’s really opened my eyes to the possibilities available.
