This is Isla and her big sister, Darcey, and mum, Georgia. For most families, summertime means going to the beach and making sandcastles, or adventures in the woods and playing with friends. For Isla and her family, escaping for a summer holiday or enjoying a day out together isn't so easy.
Isla is three years old, and she was born very premature at just 24 weeks.
“When she was born, she weighed just 517 grams,” says mum Georgia. “She was so tiny, she fitted into the palm of James’ hand.”
