Children's Hospital of Wales: 'Treating children as children'
A decade since it first opened, a significant milestone will be marked in the history of Wales' only hospital dedicated to caring for children.
The first minister will join patients, staff and celebrities to officially open the £64m second phase of the Noah's Ark Children's Hospital for Wales in Cardiff.
The project means almost all the specialisms involving children - currently provided at the University Hospital of Wales - will be under one roof for the first time.
Providing dignity and comfort to children at a stressful time is key and home comforts including computer games aim to make patients' stay more manageable.
BBC Wales health correspondent Owain Clarke talked to staff and a parent and had a tour of some of the facilities.
