My kid of 4.5 year has continue coughing problem, especially in night, after every 10-15 days problem persist, doctor is giving medication, it get resolve after medication but again get started .

A. Cough in a child could be allergic , infective or due to some other cause like GERD so it needs proper valuation before giving any ji medication . Primarily you can give steam inhalatijon to the child for the improvement before consulting your doctor.
