big hugs for your little girl
I know exactly how she feels, i was seeing a specialist for 4 years trying to control mine - was a very horrible experience!

For your little girl, the only thing i can really think of is cranberry juice and lots of it!! It has some natural antioxidant in it that helps aid in the cure, and also helps prevent UTI's. It tastes pretty nasty, quite dry like a white wine.. but its good stuff!

I hope the medicine kicks in soon, poor little sausage xxx
