My 10 week old daughter who was 8 weeks early has had a stopped up nose, coughing, sneezing and now she s hoarse. I have been using the cool mist humidifier, saline drops and the bulb. The bulb never draws out snot, but she is still so stopped up. This has been going on for 3 weeks now. We have been to the doctor several times about this. They have done and RSV test as well as a swab to test for bacterial infections, both were negative. Please let me know what I can do about this and how I can ease this for her and also when will this go away?
