A: Your baby's ears begin to grow when you're about eight weeks pregnant and are completely formed by about 24 weeks. But your baby can start hearing her first sounds -- like your heartbeat or blood whooshing through the umbilical cord -- around 18 weeks, when the bones of the inner ear and the nerve endings from the brain are developed enough. She may even be startled by loud noises!
With the technology and devices that are now available, the sound of a baby's heartbeat can be heard using specialize equipment as early as five or six weeks into the pregnancy, making the baby anywhere from 21 to 28 days old. Conception usually happens about two weeks after the period begins.
