Brief pauses, small sighs, and changing rhythm may occur during sleep, especially in the first weeks of life.

A young child’s airways are narrower in absolute diameter, meaning that even modest mucosal edema, mucus accumulation, or secretions can substantially reduce the cross-sectional area available for airflow. This narrowed lumen produces […]
