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!
What's next. Your baby will continue to use hearing to make sense of the world and to learn to communicate. Even though the sense of hearing is up and running at birth, the portions of the brain that respond to complex sounds and attach meaning to what is heard continue to develop until about age 12.
