For Lisa Hover and her husband Andy, life on the Hampshire Dorset border with their family of four children seemed idyllic. Even when a routine sight test on their young daughter Annabelle picked up an abnormality, it all seemed manageable. But the abnormality turned out to be early sight loss, which itself masked a more severe and life shortening genetic condition. With no cure available, Annabelle was determined the most from her limited life span.

Lisa talks to Dr Sian Williams about the challenges, joys and sadness she experienced - and Annabelle's dream to have a white Christmas with all the family.
