The stylish royal has been keeping busy with public appearances lately. Last week, she made a rare and moving speech at a charity event for U.K. child health organization Best Beginnings, and talked candidly about how motherhood has changed her.

"Personally, becoming a mother has been such a rewarding and wonderful experience," she said. "However, at times it has also been a huge challenge. Even for me, who has support at home that most mothers do not."

"Nothing can really prepare you for the sheer, overwhelming experience of what it means to become a mother," she continued. "It's full of complex emotions of joy, exhaustion, love, and worry, all mixed together."
