Rather than simply alerting you to your baby’s nighttime or naptime sounds, a number of baby monitors available today provide an incredible amount of information. Baby movement monitors, such as the Owlet or the Angelcare, use special sensors to track a baby’s movement while they’re sleeping and alert you to any stillness that may signal a problem.
These devices can also monitor temperature, breathing, and heart rate to give you a more complete picture of your child’s health. Some even transmit video so you can see exactly what’s going on in the crib without risking an untimely awakening by opening the door and walking into the room.
