Prince William shared a never before seen photo of his children, Prince George, Princess Charlotte, and Prince Louis from months ago.

The photos were featured in the documentary Prince William: A Planet For Us All, which centers on climate change.

In the snaps, the three young royals show off their green thumbs and their passion for planting. One of the photos shows Prince George examining a raised flowerbed with his finger.

Another photo shows Princess Charlotte holding a pot plant upside down. The adorable royal is wearing a blue sweater, a tartan skirt, and Wellington boots.

In the third photo, Prince Louis is holding a small pail while playing with the sand.

“I’ve always loved nature… but fatherhood has given me a new sense of purpose,” William says in a first-look promo for the ITV documentary. Now I’ve got George, Charlotte, and now Louis in my life, your outlook on life does change. You want to hand over the wildlife in a much better condition,” Prince William said.

Prince William also said that the coronavirus pandemic has made it possible for the public to think about what really matters in life.

“Someone has to put their head above the parapet and say, I care about this… to have the belief that if we all work together, we can make a difference,” he said.

Prince George, Princess Charlotte, and Prince Louis also joined their dad during the premiere of his documentary. They also had a conversation with Attenborough.

Days later, the young royals’ voices were heard when they asked Attenborough questions about animals.

Following their recent video appearances, Prince George and Princess Charlotte’s accents were analyzed by Professor Jane Setter, who teaches phonetics at the University of Reading.

“The accent they have, particularly George, sounds very like Southern Standard British English with some features of Estuary English. This is not unexpected as William and Harry both have features of Estuary English in their accent. The only feature of Estuary English George has in this very short clip is a vocalized ‘L’ - so a vowel at the end of 'animal' rather than the ‘L’ sound - and this is a feature of Estuary English,” Setter said.

But experts also said that Princess Charlotte’s British accent sounds posher than her siblings. She also sounds more like Middleton than Prince William.
