What should I do if my baby has a cough?

When your baby is coughing, ensure adequate fluid intake to keep the respiratory tract moist. Maintain fresh indoor air with good ventilation, as well as appropriate temperature and humidity. If the cough is mild, you may try gently patting the baby's back to help clear mucus. If the cough persists or worsens, seek medical attention promptly to determine the underlying cause. Under a doctor's guidance, medication such as cough suppressants or antihistamines may be necessary.
