The Babysense 7 movement product is a sensor pad mattress product that isn't portable but seems to have fewer false alarms than wearable products. The BabySense 7 is easy to use and doesn't require much setup or preparation outside of placing the sensor and control unit. This unit even works well after your baby learns to roll over, unlike the wearable options that become less reliable as your little one's age.
If you want to be as streamlined as possible and happen to have extra Apple devices hanging around, the Bump recommends the Cloud Baby Monitor app, which turns your iPhone, iPad, Apple TV, Apple Watch, and even your laptop into a secure Wi-Fi baby monitor. Use one device in the nursery as a camera, then have high-quality live video and audio transmitted to a secondary device, or even a third or fourth. Using the “parent unit,” you can talk to your child through two-way video and audio, turn on lullabies or white noise, and adjust the night-light on the other side. The app will also alert you to any noise and motion occurring in the other room.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
