The only thing I can think of that I try to do with DD if I think she's 'getting' sick is to keep her warm inside if it's cold out, sleep and keep b/feeding as ryatha said, and maybe if it's not too cold where you are get her out into some sunshine for a few mins when you can....I think sunshine always helps to feel like you're 'drying' up the cold, I always take DD into the sun when I can. Dunno if that helps but good luck
