Birmingham Children's Hospital is celebrating its 150th birthday with an Alice in Wonderland themed tea-party.
Youngsters who have been treated at the hospital will be there.
Amongst the guests will be Charlie Harris-Beard who had a bone marrow transplant last October.
Another former patient is Jasmine Page.
She had the first heart transplant carried out at the hospital.
In recent years the hospital has become an international centre with state of the art facilities.
The hospital cares for almost 250,000 babies and children every year.
