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.

This year, the Wales family did things a bit differently, with Princess Kate posting a message about Mother Nature versus releasing a private family photo—no doubt due to the backlash from last year's Mother's Day photo incident.
