A child’s cough is mainly related to poor resistance. Once a child has a cough, it is easy to have recurrent episodes that cannot be cured. If your child has a bad cough, you should seek medical attention to determine the cause and treat the type of cough your child has. The medical principle is to take medicine instead of injections and to give injections instead of fluids. If it is an allergic cough, nebulization treatment can be given, and if it is a mycoplasma infection, azithromycin treatment can be given. Usually, you should let your child rest more and reduce exercise, because it is easy to cough more after exercise. Eat less spicy and stimulating greasy food, drink more warm water and eat a light diet.
