CATHERINE, the Duchess of Cambridge, has returned to work from her maternity leave overnight, five months after giving birth to her third child, Prince Louis.
The wife of Prince William visited a forest school and garden to see the work being done to give children from urban London the chance to learn about the natural world.
The Duchess looked effortlessly chic as she dressed casually for the outdoor event in a warm jumper, knee-high boots and a khaki hoodie jacket.
Her solo appearance is her first engagement since she gave birth to baby Prince Louis on April 23.
Prince Louis, the sixth-in-line to the throne, was born in London on April 23.
He is a younger brother to Prince George, 5, and Princess Charlotte, 3.
The Duchess also has a charity appearance scheduled to promote World Mental Health Day on October 10.
And on October 12, she will join the rest of the royal family as they celebrate the wedding of Princess Eugenie to her fiance Jack Brooksbank, at Windsor Castle's St George's Chapel.
Catherine tonight visited the Sayers Croft Forest School and Wildlife Garden at the Paddington Recreation Ground.
The school hosts thousands of visits by London schoolchildren each year and strives to give children from the city an insight into the natural world.
Kensington Palace said the visit would allow Catherine to see first-hand the "positive impact that the Forest School has on children's emotional and physical wellbeing.''
Catherine focuses heavily on children's charities, and is also a patron of the Royal Foundation along with her husband Prince William, and her brother-in-law and sister-in-law Prince Harry and Meghan, the Duchess of Sussex.
Known as a hands-on royal, Catherine took a longer break after the birth of Prince Louis as she also wrangled her two toddlers. Her five-month break was still much shorter than the usual nine-12 months new parents tend to take in the UK.
She was back at work just six weeks after the birth of Prince George, and took two months off after Princess Charlotte's arrival.
Catherine played a prominent role in the wedding of Prince Harry and Meghan at Windsor in May, when Prince George and Princess Charlotte formed part of the bridal party.
She also attended the Trooping the Colour celebrations to mark the birthday of Queen Elizabeth in June, and attended the Wimbledon tennis tournament with Meghan, albeit in a private capacity, in July.
