The royal looked happy to be bonding with a younger crowd during her official engagement at Hampton Court's Magic Garden in West London where she opened the new children's play area. Kate brought her characteristic warmth and charm to the engagement, waving to well-wishers and the dozens of children that had come out to meet her.

As the venue is particularly suited to youngsters, the conversation naturally turned to Kate and Prince William's two adorable children, Prince George and Princess Charlotte.

The couple's son, who turns three in July, would have particularly loved to run around the Magic Garden, while cherubic Charlotte is already showing off her walking skills, as her official birthday portraits released by the palace showed.

Royal fans were hoping that George would accompany his mother to the engagement, but sadly the little Prince was absent. George was most likely attending his morning session at nursery, where he is enrolled part-time.

Speaking to the children and parents, Kate did admit that her litte boy would have loved the play area, but that he would have been "scared" of the model of the 25 foot long sleeping dragon.

PRINCESS CHARLOTTE'S CUTEST MOMENTS

"She said, 'George would have loved it,' and said that she wished she had brought him now! I guess she would have to worry about him if she had," Natalie O'Rourke, who was playing in the sandpit with her son Woody, told reporters.

Of the dragon, schoolgirl Olivia, eight, added: "She said he might be a bit scared of it."

During the visit, Kate toured the outdoor space, which featured models of battlements, towers and a secret grotto. The garden was designed by award-winning landscape architect Robert Myers, and draws inspiration from the myths and legends of the Tudor Court.

Despite the sunny weather, Kate, was wrapped up in a coat by Michael Kors that she'd also worn during her 2014 tour of Australia. She finished her look with her trusty nude heels and a small clutch bag.

Kate had a jam-packed schedule on Wednesday. The Duchess carried out her first engagement as patron of the Anna Freud Centre – a charity that supports mental health in children – by attending a lunch reception at the charity's new centre of excellence, following her visit to the Magic Garden.
