My 2-month-old son is not feeling too well, he has a stuffy nose, cough, and loos of apatite, he didn't sleep well last night. I need an advice on what to do. A first-time.
It is important to note that most cough and catarrh in children and adults are due to viral infection, which runs it's course and stops on its own. Therefore the use of medication is not necessary.

For babies having cough and catarrh you keep child warm by avoiding exposure to cold with frequent baths or cold baths or exposure to direct fan or too cold ac in the room. Avoid smoke and people with cough and catarrh. If baby should develop breathing difficulties kindly take to see a paediatrician.
