It's not even full on winter here in MI and DS has come down with his second cold.

I'm not too worried because he hasn't had much of a fever and I'd rather he build immunity while younger than in school years later (we're a grandmacare family)... anyway, is there anything else I can do?

We've been nose-frieda'ing, boogie wiping, humdifying and he's been drinking/eating like normal for the most part.

How long do runny noses/colds last?
