This was a big day, and one Isita has been looking forward to for a very long time. Ringing the end of treatment bell has made it real for her.

We made a family creation to thank the doctors and nurses on Elephant, Giraffe, Lion and all the staff throughout Great Ormond Street Hospital who contributed to Isita’s treatment. It is impossible to say exactly how many people’s skill and care have brought Isita to this point. There are 90 names in the picture. There should be hundreds and hundreds more if you count the scientists, drug developers, pharmacists, specialists of all kinds, surgical staff – and many other people whose names we will never know. However many they are, we bless and thank them all.
