Theo's mummy and daddy were so happy when they knew he would be coming into the world.
But when Theo's 20-week scan revealed that Theo had a rare and serious heart condition, a special plan was put in place to make sure he would be given the specialist care he needed at Leicester's Hospitals.
Theo's mum, Sarah, describes the difficult process that saw her seperated from the newly-born Theo almost immediately after birth.
Theo's story is just one example of why it's so important having a single, dedicated children's hospital where all of our children's services are together in one building.
Children like Theo deserve the best possible care we can give them. They deserve a new Children's Hospital.
Let's give Theo the hospital he deserves. Let's do him proud.
