"For families of children with life-limiting conditions, every moment is precious and every memory needs to be cherished and celebrated," the mother-of-two wrote.

"Children's hospices strive to create happy moments in the most difficult times any family could face. I hope you will join me in supporting Children's Hospice Week and work to make every moment count for all of our families."
