The Tommee Tippee digital sensor mat monitor is a really easy to use solution to parenting concerns about a baby's safety whilst they are asleep in their cot. Tommee Tippee understand that parents crave peace of mind when they are in a different room to their child. A parent's anxiety levels can be really high when they bring a newborn baby home and for many months afterwards. Having a sensor mat which is designed to be located underneath a baby's mattress takes away some of that anxiety. It works by monitoring the baby's movements and, if after 20 seconds this highly sensitive mat has not registered any movement, and alarm will sound. This is particularly beneficial during a baby's first few months. After the child has passed the newborn stage and begins to move around more in their cot, the monitor can then be used as an audio only unit. The audio function of this model offers clear sound and you can hear a baby within a generous 300m radius. The parent unit also enables the parent to speak to the child without actually being in the room which can soothe them, or reassure them that the parent is on their way. The Tommee Tippee monitor also includes a night light to cast a gentle glow around the room, which is comforting for baby and makes it easier for parents to move around quietly in the middle of the night. The built-in thermometer helps parents to monitor the temperature in the room as well.
