2. Postnasal drip: when the child lies down, the back of the nasal cavity is connected with the throat, and the secretions of nasal inflammation, such as rhinitis, sinusitis, allergic rhinitis, etc., may reflux to the throat, stimulate the pharynx and cause cough.
3. Bronchitis or bronchopneumonia: Children with bronchitis or bronchopneumonia have increased phlegm production in the trachea, and when the child lies down, due to changes in body position, the flow of phlegm in the trachea stimulates the mucous membranes, which can also cause coughing.
Children lying down cough, there may also be other reasons, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
