There are many reasons why children cough at night, and there are different ways to deal with different reasons. For example, the most common cause of nighttime coughing is nasal mucus flowing backwards after a cold. Firstly, we can elevate the child’s body position and pillow, and secondly, we can take oral antihistamines such as cetirizine or keratan, which can reduce the secretion of nasal mucus and backflow. If the nose is stuffy and runny, you can use a sea salt water spray to cleanse the nasal cavity, which can also prevent nasal reflux. Other causes of nighttime coughing are allergic coughs. If the cough is allergic, the main thing to do is to look for substances that cause your child’s allergies, such as whether there are any furry toys around or other objects that can easily cause allergies. Avoid these objects in order to make your child’s cough better, while mattresses, pillows, and clothing should kill mites. If the cough is caused by reflux, anti-reflux treatment or elevation is usually required, and if necessary, a doctor’s visit is necessary.
