I am glad you are taking her to the doctor. As the others suggested it does sound more like a small tear from constipation. Constipation is really all about diet and body movement, in my experience. With fiber it is much better (in terms of the body's ability to process it) to get it from food rather than in supplement form. If you don't already, you might try including high fiber foods in every meal. These would include things like fruits & veggies, whole grains, and legumes. Think things like pears, brown rice, beans, and wholesome fibrous veggies (e.g. asparagus rather than lettuce). Experiment with a variety and rotate through different foods to get the best effect. A bit more of these whole foods and less processed foods (cheese, white flour foods, meats etc), may help. Also, lots of water is important, as is getting the body movement through exercise or just running around playing outside, dance, etc. The other thing to consider is that sometimes constipation happens if one is not getting enough calories. If perhaps your daughter is going through a growth spurt or for some reason not eating a lot, that could be significantly adding to constipation problems. Hope all is better soon!
