A Surrey-based company has developed Pacifi which records your baby's temperature throughout the day via a sensor and beams the data back to your smartphone.
Parents can set up automatic alerts on a special app to warn them if the temperature rises above a certain point.
The dummy also features an in-built proximity sensor that allows parents to track the pacifier's location, 'The Telegraph' reported.
Users can set alarms on the app which are triggered when a child breaches a certain distance, which can range up to 50 metres.
The device can be purchased on the Blue Maestro website for 25 pounds.
