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!
A baby's hearing starts developing around 20 weeks after conception and by 23 weeks they are able to hear the sound of their motherâs heartbeat. Eventually as they grow they are able to hear sounds from the outside world and can create an attachment to their parentâs by the sound of their voices. Newborn babies are believed to be able to distinguish the voices of their parents because their hearing develops around 20 weeks after conception.
