sick baby. what to do?

Shauna
Ok so my 7 mo old has a cold and it's not going away. It's only been 4 days but he's getting worse. Fever, coughing, congestion, sneezing... The whole thing. So my question is what should I do? Would the dr even give him medicine or do I have to just try natural stuff and keep him pumped full of Motrin to help with fever and feeling achy. Help?!
