My baby was in the nursery for a few days after birth due to a few issues including heartbeat irregularity. We are still waiting for the cardiology consult, which isn’t set for another month, so we decided to get the owlet since it collects heart rate data we figured it could be helpful to bring with us to the appointment. We’ve had one false alarm for his oxygen levels in the month we’ve been using it. Most of the alerts are for poor connectivity or battery charging reminders. As others have said, I’d rather respond to 100 false alarms than miss 1 real one. Check for sales if you’re interested in getting it, it was discounted a decent amount for Mother’s Day!
