Puerile breathing is the characteristic bronchial-like breath sound that is heard when you listen to a child's chest with a stethoscope. Normal breath sounds in adults are vesicular, and a bronchial breath sound might signify a lung pathology. But it is thought to be normal in children because they have a thin chest wall compared to adults, which magnifies the breath sound all the way from the trachea, making it louder and more bronchial.
