Cough and runny nose

LT

Since Xmas our daughter has had an almost constant cough and runny nose. The cough is usually worse at night, and has been waking her up. When I talked about it with her doc a few weeks ago, they said she sounded healthy and it was just a thing going around. Just wondering if anyone else has been dealing with this never ending cold. Trying to decide if we need another trip to the doc.
