What were the symptoms? My 5 week old caught his big sister's cold. Symptoms started on Thursday with a stuffy nose, goopy eyes and lots of sneezing. I talked to the nurse at my pediatrician's office and she said that as long as he doesn't run a fever, and he's still eating well, it's nothing to worry about. This morning he seemed like he was getting better, because he woke up with no goop in his eyes. But tonight, he started having a mild dry cough. Just like he's clearing his throat. I assume he just has some post nasal drip from the stuffed nose. He's still nursing great and sleeping well. Should the cough freak me out, or is it just part of the cold?
