No, actually it is true. I suppose it shouldn't matter whether or not you believe me, but my original question is about elimination diets. She has a gluten reaction, maybe once or twice a year, and that's typically not my fault. That's really good for the past six years so obviously I've been doing something right with her diet. For her to be sick daily for the past week and a half is odd. My understanding has always been that celiac disease is due to an intolerance from wheat, barley, rye and sometimes oats. She has never had a problem with oats so believing that Lucky Charms is okay is not a huge mistake on my part. I have pulled it since we're not sure what is going on, but she had one bowl today, not daily for the past week and a half.
She has received a great education in her diet. She googles if she's not sure, reads books about her diet and attends camps for kids with celiac disease. If anything we are overly picky. She is capable of making mistakes, and so are we, but after the first day of being ill, we were double-checking. Nothing has changed with what we feed her.
