Question

A 5-month-old baby makes a whistling sound in their throat after sleeping, similar to snoring. Is this normal?

Answer

Based on your description, this may be a symptom of laryngospasm in the infant stage, usually caused by underdeveloped laryngeal cartilage leading to narrowing of the throat. This condition typically appears within one week after birth and is characterized by a whistling sound at the end of inhalation, accompanied by varying degrees of respiratory distress. Laryngospasm usually resolves naturally within 6 months after birth, but if there are persistent or worsening symptoms, it is recommended to consult a pediatrician for appropriate diagnosis and treatment.
