I got sick right before my daughter went to daycare with a bad cold, got better and then my daughter picked up a cold from daycare, got sick again....and then better but she still has a cold. My parents came to visit and they just caught colds, assuming from my daughter and now I am sick again. I usually get one to maybe two colds a year if that. This is crazy! And I am supposed to get a flu shot at my next dr apt, which means I will probably get sick again. Is there any other way of building immunity besides the vitamins we are all taking? Any home remedies?
