Good to know:- Thanks to graphic sound bars on the parent unit, you can tell if there's any noise in your baby's room just by looking, even when it's on mute- With the soothing night light and 5 calming lullabies built into the baby unit, the monitor will help your baby quickly drift off- The temperature sensor tells you when the temperature is too high or low, so you can adjust the thermostat and keep your baby comfortable- Use the talk-back intercom system so that your baby can hear your voice even when you're in a different room
