Hello. My 5 month old daughter has had a runny nose now for a couple of weeks. She is teething and so I thought that this was just part of it! However she now has some chest congestion and I can feel it in her lungs when she breathes occasionally. She does not seem bothered by this nor does she have a fever. She has not had any health problems before...she was a month early but born healthy after a c-section. She usually sleeps 11 hours a night and is a well tempered baby. I am a first time mom and worried about the congestion! We have been putting a humidifier in her room at night and giving her infants Tylenol for the pain with her swollen gums. I am just worried about her lungs...is there anything else I can do?
