My 5 year old always seems to have a mucousy cough. She has been diagnosed with pneumonia 3 times, bronchitis a couple of times, ear infections (tubes) and croup. I am really concerned about the mucousy cough because I feel like it is just an infection waiting to happen. Her cf test came back 48 and they have checked for immune deficiencys in the Igs. Nothing yet. Am I over the top thinking she shouldn't be like this? She has been on Zithromax since last wednesday and pulmicort nebs three times a day. What else should I do?
