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!
Signs of hearing loss in infants vary by age. 1  A newborn baby with hearing loss may not startle when there is a loud noise nearby. 2  Older infants, who should respond to familiar voices, may show no reaction when spoken to.  Children should be using single words by 15 months, and simple 2-word sentences by age 2.
