#AskTheExpert Hello, my son is 3 years 7m old. Almost a month back, he had a cold (wet cough and running nose). After a week it reduced (medication: Ibugesic and Masyrix syrup). then again it was seen after a week and this time, our doctor asked for antibiotics. it got reduced in a week. but from Last 1week, again we are seeing his nose is wet (thick mucus) and getting cough only at night. can you please suggest what to do .
