My 19 months old boy had got severe cough and cold. He was diagnosed with pneumonia and he was admitted in hospital for 5 days. Post that he got discharged, he was recovering. After 12 days from discharge, he again got cold and cough. Again the same symptoms are seen. What to do? Doesn’t this pneumonia go off at one time or does it keep coming for my little one? Please help me, I am very much worried
