My 10 month old baby has recently developed light white discoloration on her cheeks. what cud be the reason. showed it to doctor he prescribed mometasol but isnt helping much

Well! I think you must consult another doctor as one can advice for general cough and cold as what home remedies can be done but one should visit a doctor if something else other than normal day today ailments bother. But I am sure it would be something that be fine with medication or perhaps some supplement as it may happen because of lack of some nutrients in body.
