The baby's cough and expectoration are considered to be caused by respiratory tract infection. It is suggested that parents can increase the amount of drinking water for the baby, which is helpful to dilute sputum and relieve cough symptoms. If the baby's cough and expectoration are serious, take the baby to the respiratory department and use budesonide and acetylcysteine aerosol inhalation according to the doctor's advice.
