He's barely just celebrated his first birthday on April 23, and now Prince Louis is walking! The royal toddler - who turned one on April 23 - showed off his new skill during a fun day out with his siblings Prince George and Princess Charlotte and mom and dad Kate Middleton and Prince William. The family dropped by the Chelsea Flower Show - the world's largest garden and flower exhibition - to visit a garden that was specially designed by the Duchess herself, with children in mind.

Kensington Palace released a series of pictures of the royals by Matt Porteous during their trip to Kate's Back to Nature garden - which she worked on with the help of award-winning landscape architects Andrée Davies and Adam White. And it's clear to see the mini VIP visitors were more than impressed with the results of their mom's hard work.

This is the first time we've seen Prince Louis walking - and he sure does look confident! The toddler zooms off on his own brandishing a twig under the watchful eye of his papa William while his older siblings go barefoot to climb up the waterfall behind him.

 

A royal source told HOLA!'s sister publication HELLO! "The Duchess wanted to show her children what she has helped to create. She’s spent a lot of time on this and they have noticed. Naturally she wanted them to try out the garden and its features."

Charlotte and her five-year-old brother George take a moment to dip their toes into the stream while dad shows Louis the fire pit between two dens built from Hazel branches the family collected themselves.

 

At the heart of the garden is a nine-tonne treehouse built on a huge chestnut trunk and clad in Staghorn Oak, Larch and Hazel branches. A ladder gives access to a viewing platform over the rest of the garden.
