Abstract: A child monitoring device has a plurality of sensors to sense data relating to a child to be monitored, a wireless communications unit and a processing unit. The processing unit is able to receive signals from the sensors, receive data relating to the child input via said wireless communications unit, cause the wireless communications unit to wirelessly communicate with an external database to receive data, process the signals received from said sensors to determine child development conditions, compare determined child development conditions with the data received from external database, and cause said wireless communications unit to transmit messages containing child development information for reception by an external device.
