A child’s night and morning cough may be caused by cough variant asthma, allergic cough, gastroesophageal reflux and other diseases. 1. Cough variant asthma: the child’s main symptom is irritating dry cough, most obvious in the early hours of the morning and at night, so the child will have a cough in the morning at night. 2. Allergic cough: the child will have symptoms such as cough and foreign body sensation in the throat, and the cough will appear during the day or at night. Therefore, the child will have a cough at night and in the morning. 3. Gastroesophageal reflux (GERD): the child will have epigastric pain, cough, belching and reflux. As a result, the child will have symptoms of night-morning cough. Parents should take their children to the doctor in time to find out the cause of the disease and follow the doctor’s instructions when their children have symptoms of coughing in the morning at night.
