Are you sure the baby is still breathing? ARE YOU SURE?! Every new dad has one or two or 400 moments when he’s not. Rest easy (or at least easier) with the Owlet, a soft sock baby monitor that slips on your baby’s foot and sends heart rate, oxygen levels, skin temperature, and sleep quality/position data to your smartphone. You can also opt to share your baby’s vitals with researchers, to help prevent the thousands of unexplained infant deaths each year.
