With my first two babies, I had a noise-activated baby monitor with a video screen. And often I would just sit and watch their chest rise up and down or touch them to make sure they were fine which inevitably woke them up. When I got pregnant with my third child I was in need of new monitor and I purchased the Owlet, a unique monitor that the baby wears as a sock that monitors oxygen and heart rate. I love my Owlet. I can check her vitals on my phone so no more waking baby up to see if she is breathing. For me, this device gives peace of mind and deeper sleep (for mom) which is priceless. Another plus is the customer service at Owlet is amazing.
