I've heard that some people use a stethoscope to check their babies' heartbeats. How does it work?

The stethoscope is used to listen for the sound of the baby's heartbeat. It’s a medical device that allows doctors and nurses to hear the sounds of the body. The stethoscope is made up of two parts: a chest piece, which is placed against the skin, and a headpiece, which is placed over the ears. When the doctor or nurse hears the heartbeat, they can tell if the baby is healthy and developing normally.
