Newborn hearing screening is important because early detection of hearing issues is critical for a child's development. Since approximately 1-3 babies per 1,000 are born with some degree of hearing loss, identifying these issues early allows for timely intervention that can significantly improve speech, language, and cognitive development. The screening is quick, painless, and typically performed shortly after birth. Even if a baby passes the initial screening, it's still important to monitor their hearing development, as some children can develop hearing loss later due to illness, medications, or genetic factors.
