All the Details of Duchess Kate's Visit to the Anna Freud Centre

Watch the mother of two join a drumming circle and share smiles with children.

— -- The Duchess of Cambridge showed off her maternal instincts today, charming a bunch of students and offering big hugs to kids at the Anna Freud Centre Christmas Party.

The future Queen joined the kids drumming in a rendition of Queen's "We Will Rock You," and helped with a Christmas tree collage.

The Anna Freud Centre is one of London's leading institutions for children with mental health needs, and Kate has made mental health awareness and arts education the cornerstone of her charitable mission.

The Duchess has stressed the importance of early intervention for children struggling with mental challenges and the benefit of arts education to build confidence.

"Her Royal Highness is keen to draw attention to the ways this charity is working to lead a step change in children and young people's mental health care," a Kensington Palace spokesperson said. "The visit reflects the Duchess's continued interest in child mental health issues and the importance of early intervention and working with the whole family to provide children with in school mental health services."

Looking every inch the Princess in the brilliant, red Alexander McQueen dress she wore during the Queen's Diamond Jubilee celebrations, Kate again showed off her new haircut which has woman already hitting the salons around the world hoping to get the repli-Kate look.

The holidays are proving to be a busy time for the Duchess, who will spend Christmas at Anmer Hall with Prince William, Prince George and Princess Charlotte. But first, she wanted to encourage the children at Anna Freud Centre before they too left for the holidays and to remind them of the progress they've made during the school year.

The Anna Freud Centre seeks to provide alternative therapy for children with mental and behavioral issues at home. It works with families to help the young students over one their disability and employs confidence building in a safe environment.

Kate last visited the school in September, marking her first solo visit there after the birth of Princess Charlotte. She and Prince William have been on a mission of sorts to raise awareness among a number of charities who all promote the mental well being of children including tackling online bullying.

"Her Royal Highness is keen to draw attention to the ways this charity is working to lead a step change in children and young people's mental health care," Kensington Palace said.
