Prince Louis Takes His First Public Steps in Kate Middleton's New 'Back to Nature' Garden (Photos)

The one-year-old prince Louis looked all grown up as he was spotted walking around for the very first time in public.

Prince William and Kate Middleton took their children – 5-year-old Prince George, 4-year-old Princess Charlotte, and Louis – for a day out at Middleton’s “Back to Nature” garden.

Kensington Palace’s official Twitter account posted a video on May 19, revealing the royals enjoying at the woodland-themed garden.

The video shows all the young royals running around and exploring the garden including the youngest child of the Cambridges, Prince Louis.

The youngest royal sported the familiar striped hand-me-down shorts, which is the preferred outfit of choice for the young princes. At one point, he is even seen enjoying a single-rope swing that hung from the gradern’s centerpiece.

The Palace tweeted that the garden was created in the hope of inspiring and encouraging people to enjoy outdoors and nature.

Amid other several released photographs, one shows George and Charlotte enjoying a small creek running through the garden. Another one shows Middleton herself reaching out for the clean water.

Middleton stated, "I hope that this woodland that we have created here really inspires families, kids, and communities to get outside, enjoy nature and the outdoors and spend quality time together."

The Duchess explained that she recently came to know that about 90 percent of the adult brain develops before the age of five. So what a child experiences in those early years has a huge role in how their brain develops.

Middleton believes that it is important to spend “quality time with children and babies from a really young age.”

She further stressed, “I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young kiddies.”

Besides her own children, the Duchess was also accompanied by local schoolchildren, with whom she engaged in outdoor activities including reed boat baking and marshmallow toasting.

Middleton designed the garden, in collaboration with Adam White and Andree Davies, for the “Chelsea Flower Show.” It carries the theme of woodland wilderness and it aims to “get people back to nature.”
