The baby coughed and vomited at night and it was fine during the day. It may be caused by allergic cough, and it may be caused by chronic pharyngitis. The child should drink more water to ensure that the throat is moist, and go to the pediatrics of the regular hospital for laryngoscopy. If it is diagnosed as chronic pharyngitis, it can be treated by ultrasonic atomization inhalation.
