Just the other day, thanks to a photo published by the Prince and Princess of Wales, the public got a glimpse of what little Sienna looks like.

In a few days, Princess Eugenia posted another picture and showed how children watch penguins in the London Zoo.

Evgenia shared the photo in honor of Earth Day.

In addition to this shot, she also shared a selection of other photos to celebrate the annual event.

"Today is World Earth Day and today we're talking about our planet and the people who are doing amazing things to help protect it," Princess Eugenie began in the caption of her post, before describing what each photo she shared showed.

"August and his cousin Sienna love going to London Zoo. It's part of the Zoological Society of London @zsllondonzoo, a global wildlife charity that helps restore the environment and protect wild animals," she said, detailing the first photo.

"Every time you come, you support their work," added the princess.
