The object of this invention is to make life easier for the newborn parents. Heartbeat sound is known to produce a calming and soothing effect particularly when it is the mother's identical heartbeat which the infant came to know during gestation. Mothers, in general, prefer that their newborn listen to their own heartbeat, sound recognized by the infant, and not a composite of several ones as used in Hughes', mores, to an artificial or simulated heartbeat as described by numerous inventions. This invention provides a practical method for the mother to record her own heartbeat, which is played back by a device automatically activated by the crying of the baby. The object is to lure the baby into believing that his/her mother is present when needed based on hearing comforting familiar heartbeat even though she is not physically present. The recorded mother's heartbeat is achieved by the use of a stethoscope fitted with a diaphragm in one end of the acoustical tube and the other end plugs in a microphone record of the device. The mother may rep eat her recording to obtain best results. The parent will place the device besides the crib, on standby mode, the sound is played back activated by the crying of the baby and remains activated until a pre-determined time interval of about 6 minutes after the crying has stopped. Continuous playback may be obtained by switching On S1, in FIG. 1a. Periodical checkings on the newborn are strongly suggested.
