Infant monitoring refers to the use of devices and systems designed to keep track of a baby's health and safety. These tools can include video monitors, audio monitors, and wearable devices that track vital signs like heart rate and breathing. The goal is to provide parents with peace of mind by alerting them to any unusual activity or potential issues. Many modern infant monitoring systems also connect to smartphones, allowing parents to receive real-time updates and notifications. Some devices even offer features like temperature monitoring and sleep tracking, helping caregivers ensure that their baby is comfortable and healthy throughout the night.
