6 months baby coughing

My baby has been coughing for more than a month. Apparently theres no remedy for it. Ive tried so many things. Kkh did not give any medication, kids clinic gave abrilar which doesnt work at all. They also say baby will just heal by themself. And yes puke, and they told me the only way baby expel the phlegm is to vomit it out. Does you baby attend ifc ?

Visit the doctor and if needed treatment they let you know. Usually no med.
