Evaluate her dairy consumption - that can cause that problem in sensitive kids. Also, you might consider that she's developing celiac or gluten intolerance - the symptoms like that appear long before the end stage disease that would impact her overall. Also, loose stools are the body's way of detoxifying, so it's possible she ate something that was bad, etc. If it last more than a few more days (AND the stools are very frequent), you do need to get her to the doctor.
