The child does not cough during the day, but at night he coughs badly as soon as he goes to bed.

Children who do not cough during the day and cough at night may be caused by factors such as low indoor temperature, allergic cough, inhalation of foreign bodies, cold air stimulation, and decreased immunity. They should be admitted to hospital for respiratory examination. If allergic cough is diagnosed, they should be admitted to hospital for treatment with antihistamines and cough medicines as prescribed.
