Fellow mommies, I need advice on a sick baby!

My daughter is almost 5 months old. I'm pretty sure she has a cold which she unfortunately got from me. Her nose is running (which I suction regularly), she's coughing, and she's not wanting to eat much and having trouble sleeping. I have a humidifier constantly going and some baby vaporub. I'm thinking about calling her doctor tomorrow, mainly because of the not wanting to eat factor. What do you do for your little ones when they have colds?
