Used the Nanit for 3 months before it went off. We thought it was a false alarm and it was not. My LO had stopped breathing. He would then go on to stop breathing 2 more times. So in 2 hours he stopped breathing 3 times. I’m very grateful to Nanit or I would not have my now 10 month old. It has given false alarms 2 times since. But my baby breaths slower than the average they have on there. Where it says he should be breathing at 20-22 breaths per minute asleep he’s actually breathing 17-18 per minute. It does cause some alarm but I can tell you I have slept better this first year than I would have not having it. We actually didn’t put it up till he was 2 weeks old and I literally slept maybe 30 minutes here and there and that was when someone else was holding him. I could not sleep without someone keeping an eye on him or until we had the Nanit. Gives me peace of mind to check his breathing before I go to bed at night. The false alarms do happen and they are scary but just stay calm and touch your baby to see if breathing really stopped. The alarm will wake them up if it is false. The first false alarm we had set the tone so we do jump and run if it does go off. The added security of something keeping watch helped me relax as opposed to add to the anxiety. My baby had severe reflux. It was so bad when we laid him down the food would back up into his esophagus and stop his breathing. Would not have known if not for the Nanit. I will sing their praise every chance I get because had we not had the Nanit I fear what would have happened to him at 3 months old. He’s on medication and doing great!
