Vanellope Wilkins is lucky to be alive. The three-week-old baby was born with her heart outside her body - but after three operations, is doing well.
Her condition was discovered in a routine scan when her mother Naomi was just nine weeks pregnant. She was told her baby had almost no chance of survival, but decided to carry on with the pregnancy.
Vanellope cried a lot after she was born, which gave her parents hope. Her first operation, done when she was an hour old, gave her medication and began to open a space in her chest for her heart. It then took two weeks and more operations for the heart to get into the right place in Vanellope's chest, and to cover it with skin. She will need more operations as she grows.
Babies born with this condition have less than a 10 per cent chance of surviving.
Vanellope was named after a character in a Disney film, Wreck-It Ralph. Her father explained: "Vanellope in the film is so stubborn but she turns into a princess in the end."
