What should I do if a 7-month-old baby has severe coughing at night?

A 7-month-old baby has severe coughing at night. The following measures are recommended: 1. Take the child to see a doctor promptly to identify the cause and rule out any underlying illness. 2. Gently massage the child, as massage can promote blood circulation, improve the respiratory system, and help relieve coughing. Feed the child warm foods such as porridge or soy milk, which can soothe and moisten the throat. 3. Keep the child in a quiet, warm environment, especially during nighttime sleep, ensuring the indoor temperature is not too high. 4. Give the child warm water daily to help loosen and expel phlegm, thereby reducing cough symptoms. If the child's cough persists or worsens, seek medical attention promptly to avoid delaying treatment.
