What do you do when you're sick?

I'm currently sick with a pretty terrible cold. Chest congestion, stuffy nose, sore throat and fever.

I dont want to get my son sick and all he wants is to be held to go down for his nap. (He is one) I don't want to hold him to close to me for a long period of time and rock him to sleep and risk him getting sick.

What do you mommas do when your sick and are trying to keep your little one from catching it?
