M.B.
I know you said it wasn't your diet, but my daughter is allergic to milk and she has reflux. At least half of all packaged foods have milk added to them, so it's difficult to cut out dairy, even if you think you don't eat any :) I had a few "accidents" at first, like frozen fish (in the breading) and wheat thins crackers. Once I went completely dairy-free and my daughter started Prevacid, her gas went back to normal and was less frequent. Her poop got a lot better too! You could always ask the Dr. They're used to weird poop questions!
