Thank you so much for all your replies. We saw the doc today. He is going to try her on Hypertonic saline. She did her first dose in the office already. Maggie was coughing ALOT from the HS. So now we're going to mail in the script for HS and see if it helps her. Also, they did a culture to make sure she's not culturing something new. If her coughing get worse or keeps her up at night, I 'll bet they'll put her on an antibioitic.
