Okay. I have had maybe a week total out of the past 2 months where I didnt have a cold or some cold symptoms. It is making me CRAZY!!

I work at an early childhood center with 4 year olds in the am and 21/2-3 year olds in the afternoon, so colds are expected, but for 2 months this is nuts!

Does anyone have any advice what I can do to maybe not be so likely to catch absolutely every cold that goes around? I have increased my vitamin c intake by alot, but mostly through my diet. But I am making tylenol rich buying the severe sinus pills they have, and boiling water for steam like 3x's a day. haha Im at a loss!! Any help would be appreciated!
