Anyone else's DC's get colds without a runny nose? DS's nose never runs - I mean never and it never has. I find this really odd! He can't really blow it very well either and even when he does, nothing really comes out. The only clue I get that he has a cold is that his eyes look a bit red and then the dreaded coughing starts and goes on for weeks. It's almost like his body is surpressing the cold and holding it in. Anyone experienced the same?
