Rhiann's cause

My 6year old granddaughter Rhiann has been diagnosed with a rare brain tumour. That is affecting 7 parts of her brain. This friday 19th june 2015 she will be having a chest line fitted & is due to start an 18month course of chemotherapy next Wednesday 24th June 2015, at the Royal Marsden hospital . This will be followed by 6 weeks of radiation treatment. We as a family are totally devastated.. Our aim is to raise enough money to  be able to take Rhiann to her dream place, Disney World & also for fun days out for her.. She is already going through a lot with having daily seizures & has so much more to go through :( if you could help us with reaching our target ++++, it would be very much appreciated....
