If your baby's chest appears to sink in during inhalation and they are experiencing noisy breathing, it could be a sign of respiratory distress or a condition such as airway obstruction or bronchiolitis. This phenomenon, known as retractions, indicates that the muscles are working harder to breathe. It's important to monitor for other symptoms like wheezing, coughing, or difficulty feeding.
