I think I would try Gerber Apple-Prune Juice first. It workd wonders on my 8 year old. There is also high fiber foods to try. It will be less expensive than the doctor. He will probably tell you the same thing. And, if she doesn't start to go, the next step would be to put her in the hospital where they will give her enemas - which you can also do at home. Once she goes, the key is to keep her regular and starting with her diet it the best way to do that.
