Why does an infant breathe with loud, raspy sounds?

Many parents observe rapid breathing in their infants while they sleep, which often causes concern—especially among first-time parents. Why does an infant breathe heavily and noisily?

Why Does an Infant Breathe Heavily and Noisily?

Heavy or noisy breathing in newborns is primarily attributable to two causes. First, it may result from congenital laryngeal stridor. Due to their young age, newborns’ tracheas are not yet fully developed, leading to airway narrowing, spasms, and snoring. As the child grows older and receives adequate calcium supplementation, most cases of congenital laryngeal stridor gradually improve; thus, parents need not be overly anxious. Second, it may stem from asthmatic bronchitis. In infants with an allergic constitution, exposure to pathogens such as viruses or bacteria can trigger respiratory wheezing, manifesting as audible wheezing or stridor. In such cases, prompt medical evaluation and nebulized inhalation therapy are essential.

Additionally, using a pillow that is too high for an infant may impede normal breathing and cause tachypnea. Calcium deficiency in infants can also lead to laryngomalacia (softening of the laryngeal cartilage), resulting in rapid breathing. Therefore, identifying the underlying cause is crucial before initiating targeted treatment when tachypnea occurs.

If tachypnea is caused by calcium deficiency, oral vitamin AD soft capsules may be administered under a physician’s guidance. Additionally, regular sun exposure is recommended, as ultraviolet light helps promote calcium absorption in infants. We hope this information proves helpful.
