Prince Louis is officially walking!
In celebration of Kate Middleton designing the RHS 'Back to Nature' Garden at the Chelsea Flower Show this year, Kensington Palace have released the most adorable new images of Duke and Duchess of Cambridge and their children Prince George, 5, Princess Charlotte, 4, and one-year-old Prince Louis privately visiting the display.
In the heart-warming snaps - which were shot by Matt Porteous - the doting parents can be seen playing with their three children, while one image shows their youngest son taking his first public steps!
According to Kensington Palace, over the past months, Prince George, Princess Charlotte and Prince Louis have "helped The Duchess gather moss, leaves and twigs to help decorate" the garden.
They added: "Hazel sticks collected by the family were also used to make the garden’s den."
The Duchess told the BBC in her first solo television interview: "I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children.
"I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together."
The 'Back to Nature' Garden was designed in cooperation with award-winning landscape architects Andrée Davies and Adam White.
The world-famous show will be officially opened on Tuesday.
