Kate Middleton is taking a stand for adolescent mental health. The Duchess of Cambridge recently opened up about her work with Young Minds Matter, revealing why the charity is so important to her as well as what steps she and Prince William, The Duke of Cambridge, have taken to ensure their two children feel comfortable discussing their mental well-being.

Middleton, 34, was invited to serve as guest editor for the Huffington Post, penning a detailed blog about Young Minds Matter and the importance of mental health resources for children. In the post she introduced the fledgling campaign to readers, sharing that, in her mind, mental health and physical health in young people should be held in the same regard. Middleton added that as the mother of two children, Prince George and Princess Charlotte, she and her husband make sure to prioritize talking about feelings. She wrote that they will provide them with the tools they need to be both sensitive and supportive.

"Like most parents today, William and I would not hesitate to seek help for our children if they needed it. We hope to encourage George and Charlotte to speak about their feelings, and to give them the tools and sensitivity to be supportive peers to their friends as they get older," Middleton wrote. "We know there is no shame in a young child struggling with their emotions or suffering from a mental illness."

This is not the first time Middleton has advocated for children's mental health. On Feb. 8, during Children's Mental Health Week in the United Kingdom, she released a video in which she and four young people discussed the most common mental health issues facing their generation. As was reported by E! Online, in the heartwarming and informative video Middleton asks the kids featured about discussing their feelings with their parents. The children each share with her that they sometimes are able to speak with adults, like their moms and dads, about how they're feeling, but not always. It is then that Middleton stresses the importance of speaking with friends, suggesting that it can be helpful.

In addition to her advocacy work, Middleton has been working closely with the Royal Air Force Air Cadets — a job which Prince George, 2, is particularly fond of. After attending the 75th anniversary of the Royal Air Force Air Cadets, Middleton shared a photo of some of their planes with her firstborn. As People magazine reported, he has been "obsessed" with them ever since and hopes to sign up when he's old enough.
