Mother's Day arrives a few months early in the UK and the royal family is celebrating accordingly (even the ones that live in California.)

Since going public with her cancer diagnosis, the mother-of-three has sought comfort from the natural world. In July last year, Kate, who is now in remission from cancer, spoke about the "power of nature" as she helped to launch the Natural History Museum's Urban Nature Project.

After navigating what has been one of the most challenging periods of her life, Princess Kate certainly deserved a day of simple pleasures as the Royal Family celebrated Mother's Day on Sunday, March 30.
