Peace of mind, I own the Owelet, but I’m one of those paranoid parents, I needed something extra to monitor her breathing, I fount the sense u and decided to give it a try and I honestly can say every parent should own one . She was crying at night constantly, I didn’t know she was cold until the sense you detect the temperature, yes she was warm but not warm enough, now I know the perfect temperature for her to sleep comfortable. 2 nights ago the alarm for breathing went off, when I checked on her, it looked like she was so deep asleep that she forgot to breathe I moved her to sleep on her side and she started breathing normal again. Idk if this device saved my daughters life for sure, but I can say I sleep a lot better knowing I have the sense u notifying me if something is wrong. I absolutely love it and recommend this product.
