What should be done for a child with bronchitis who has persistent coughing?

When a child suffers from persistent coughing due to bronchitis, parents should take proactive measures: 1. Ensure the child gets adequate rest and avoid strenuous activities or overexertion to reduce triggers of coughing. 2. Maintain good indoor ventilation to minimize air pollutants that may irritate the child's respiratory tract. Additionally, offer warm water in moderation to help thin mucus and facilitate its expulsion. If the cough is severe, cough suppressants may be used under medical guidance, but attention must be paid to proper dosage and duration of medication. 3. Treat the underlying cause of bronchitis—such as infection or allergy—specifically, to address the root cause and relieve cough symptoms effectively. If the condition continues to worsen or shows no improvement, prompt medical attention is necessary to prevent treatment delays.
