“Creating magic with my girls when they were young is what brought many of my children’s book characters to life.
“Being able to now share that with my grandchildren and with children around the world has been an unbelievably special gift.
“Every time I pick up one of my children’s books, I can feel all of that precious time spent together.”
It comes as the duchess’s second cancer diagnosis shocked royal watchers worldwide when it was announced last month.
An announcement on January 21 said that Sarah was diagnosed with malignant melanoma, an aggressive form of skin cancer, which was discovered during her treatment for breast cancer.
The royal previously spoke about her diagnosis as she thanked well-wishers and medical staff for the outpouring of support she has received.
In another Instagram post, she wrote: “I have been taking some time to myself as I have been diagnosed with malignant melanoma, a form of skin cancer, my second cancer diagnosis within a year after I was diagnosed with breast cancer this summer and underwent a mastectomy and reconstructive surgery.
“It was thanks to the great vigilance of my dermatologist that the melanoma was detected when it was.
“Naturally another cancer diagnosis has been a shock but I’m in good spirits and grateful for the many messages of love and support.”
