Owlet Smart Sock
Until the Owlet technology launched, the main choice of monitor was either video and/or breathing pads.
These alternatives provide some level of security, however a visual image of a sleeping baby doesn’t necessarily tell you about your baby’s health. Further, the video feed needs visual assessment by the parent to determine if things are OK. This means that at night, you need to wake up completely to really look at the picture.
As for the breathing pads, it is quite normal for babies to hold their breath, so such a sensor may activate its alarm and frighten you, when in fact all is well.
We feel that the Owlet Smart Sock provides the greatest level of assurance thanks to the pulse oximeter technology applied.
