We use the Nanit! We have twins that were 10 weeks premature. I wanted the owlet too because I was so used to them being monitored for their breathing and oxygen saturation and I was very anxious. I will say that all the drs and nurses were very adamant about NOT using the owlet. No evidence to support that it reduces SIDS and even the most advanced monitors at the hospitals get false readings or go off when baby is moving or squirming in a particular way. If you want it for your peach of mind I totally understand that! But it tracks breathing, HR, and oxygen saturation which can provide false readings more often. I still wanted the peach of mind so we settled on the Nanit. It just monitors breaths per minute using the camera. We have gotten false readings but at least we were able to check on them and make sure they were breathing. Making sure we were following safe sleep guidelines was my biggest peace of mind.
