An Oxford children's hospice said it is "so delighted" following the announcement that Queen Camilla will continue as its patron.
The announcement of the Queen's support for Helen & Douglas House comes on the first anniversary of the coronation.
Helen & Douglas House delivers care and support to families with terminally ill children in varied settings - its hospice, hospitals, and at home - 24 hours a day, every day of the year.
The hospice also supports families through the grief that follows their child's death.
Jane Long, chief executive of Helen & Douglas House, said: "We are so delighted The Queen will continue to be our patron and I am sure our families, staff and volunteers will also be thrilled to hear this news too.
"The Queen is very approachable and friendly when we meet her, and Her Majesty has a genuine interest in what we do and the families we support as well as our staff and volunteers and the vital role they play.
"She shows great compassion for the work we do and to our families going through such difficult times.
"Her Majesty puts people at ease straight away and has a particular affinity with the children.
"She always makes them smile and they love to talk to her.
"When we meet her, she wants to understand more about the challenges our families are facing and how we help them."
Her Majesty's relationship with the children's hospice started in 2007 when, as the Duchess of Cornwall, she became patron for the first time.
Throughout the past 17 years, a key feature of her patronage has been the annual tradition of inviting families and staff from the charity to decorate Clarence House's Christmas tree.
The children get to choose decorations and decide where to place them on the tree.
Some put up the decorations themselves while others get assistance from the Queen's Equerry using his sword.
The day also features a lunch served by the Queen, a chance to meet reindeer, and renditions of Christmas carols by the Welsh Guards Brass Band.
Over the years, The Queen has made several visits to the hospice, her most recent visit being to its newly developed hospice garden.
Ms Long added: "Our visits to Clarence House and her visits to the hospice mean the world to us all and create such wonderful memories for our families, in particular, to treasure forever.
"These visits also create a lot of media coverage which helps us raise awareness of the charity which enables us to provide vital support to local families with terminally ill children."
