When last we touched this topic, she had started coughing again. The M.O. is thus: 1. we get her coughing under control, thus far it has/had been exclusively through medicine. 2. She's fine. 3.She gets a cold (I am starting to think it is actually allergies) consisting of runny nose and a wet cough. 4. Around 1-2 weeks the wet cough subsides as it would with a cold, but then the dry cough begins. 5. Dry cough goes on forever, until we beat it down with medicine.
So, what did we do this time? As it went to *the* cough pretty quickly, consisting of hours of coughing including the middle of the night, we put her back on Ranitidine ASAP. And, simultaneously, cut out ALL dairy (have I mentioned that most margarine contains dairy - I have found one version of one brand that doesn't? And thank you Whole Foods and Fresh Market for carrying dairy free chocolate!) When the coughing was pretty well over and a good 3 weeks had passed, we took her off the meds again. Sure enough, within 3 days she had a runny nose and cough. BUT this time the cough subsided on its own (so maybe it was a cold?). I waited a good extra week before writing so as not to tempt fate. She is still coughing about once a day, which makes me think maybe it's dairy plus something else, but the something else is very mild.
Last weekend we reintroduced butter only, to see how far this thing goes. I know several lactose intolerant people who consume butter with no problem, and my own dairy issues don't touch butter, so we're really hoping. She had a couple of "excursions" with baked goods that likely had some dairy in them in the last few weeks, too. Will report back on what happens.
