Babysense 7 Baby Sleep Breathing Movement Monitor for Newborn and Infants, No WiFi, Non Wearable, Non Contact Monitor with 2 Under-Mattress Sensors for Full Crib Coverage, FSA Baby Monitor

My first didn't do this so it was a real shock when my second did. It's normal though. If you're having a hard time believing it and sleeping maybe try an Owlet sock or one of these breathing monitors: Sensitive motion detection alerts you to no movement, providing peace of mind for new parents. Check it out on Amazon - you won't regret it! https://a.co/d/07VIGjRZ
