I have a very precocious 4 year old daughter. She started coughing about a month ago. We have a pet rabbit that all 4 of us are allergic to but haven't had the heart to get rid of. Because of the allergies, we keep the rabbit outside most of the year, but once it got cold, we brought her inside. We all immediately started having trouble with our allergies, including my daughter who developed a mild, shallow sounding cough. After having the rabbit inside for about 4 days, we moved her out to an inclosed sunroom with an electric heater. The rest of us cleared up immediately, but my daughters cough has persisted. My husband thinks she may be faking at this point, or that maybe what began as a genuine cough has turned into a nervous habit. The cough has not improved or worsened, and she doesn't cough when she is sleeping. It does seem to be involuntary most of the time. (Sometimes it seems that she is doing it on purpose, but mostly she does it when she is doing something else like watching tv or reading books, or otherwise concentrating on something else.) There are absolutely no other symptoms. It is a very shallow cough, it seems to be from her throat, not her lungs, but her throat looks fine. I am thinking about taking her to the doctor, but I thought I'd see if anyone else had any similar experiences. In the beginning I gave her Mucinex a couple of times, but it seemed to have no effect whatsoever, so I stopped giving it. Any ideas?
