S.,
If it has any consistency, I would not worry yet. What the doctors consider diarrhea has to be like water, no color and pure liquid. If there is color and liquid to it, wait it out a little longer. Maybe she is becoming allergic to some food, keep a log of what she eats every day. If there is a day that she doesn't go, most likely the doctor will not be too concerned. Log in what she eats, when she goes, how it looks, and how loose it is.
There is a stomach virus going on, some people get the barfing and runs, some only the runs.
If you have pomegranate take the skin, and boil it for maybe half an hour, then take that water when it cools off and add a little honey to it (so it will be sweet to her) and let her drink a little here and a little there, all through the day.
If it get's worse and you see that it is just liquid, take her to the emergency room and let them do whatever tests are necessary.
We had the virus at my house and that's what we all drank, except for my boys, my husband, my daughter and I caught it!!!
Best wishes
