“Remembering my mother, today and every day,” the Prince of Wales captioned the throwback photo shared on Sunday, March 15

Prince William is paying tribute to Princess Diana on Mother’s Day in the U.K.

The Prince of Wales, 43, marked Mothering Sunday on March 15 by sharing a photo taken during his childhood on Instagram. The snap taken in a field of flowers at Highgrove in 1984 showed Prince William, then age two, holding hands with Princess Diana, who would’ve turned 65 on July 1.

“Remembering my mother, today and every day. Thinking of all those who are remembering someone they love today. Happy Mother’s Day. W,” he captioned the photo from his private collection.

Prince William was 15 when his mother died in 1997.

As families across Britain honored mothers and maternal figures, King Charles and Queen Camilla also shared a tribute on Instagram.

“Wishing Mothers everywhere, and those who might be missing their Mums today, a restful Mothering Sunday,” they captioned photos of Queen Elizabeth II and a snap of Queen Camilla with her late mother Rosalind Shand.

Princess Kate, who shares Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7, with Prince William, didn’t post a public Mother’s Day tribute on the Instagram account she shares with the Prince of Wales.

However, she has long spoken about how central motherhood is to her life — something that has become even more meaningful following her cancer diagnosis and amid her recovery.

In 2025, the princess used the holiday to reflect on the healing power of nature during a difficult year.

“Over the past year, nature has been our sanctuary,” she wrote in an Instagram post at the time, alongside a video of peaceful outdoor scenes.

“This Mother’s Day, let us celebrate Mother Nature and recognize how our bond with the natural world can help not only nurture our inner selves, but remind us too of the role we play within the rich tapestry of life,” she continued, concluding the post with. “C.”

The nature video came a year after Kate made headlines when she released a new photo taken by William that showed her seated in a chair surrounded by the couple’s three children.

The image received extra attention as it marked the first time seeing the princess in several weeks, as she was recovering from a “planned abdominal surgery” that took place in January 2024. However, less than 12 hours after the photo was shared, major agencies began pulling the photo due to suspicions of manipulation.

A spokesperson for the Associated Press released a statement to The Telegraph, saying, “The photo shows an inconsistency in the alignment of Princess Charlotte’s left hand,” while others noticed alignment issues on clothing as well as blurred areas on the image.

Kate publicly addressed the Photoshop controversy a day later, saying in a statement shared on social media, “Like many amateur photographers, I do occasionally experiment with editing. I wanted to express my apologies for any confusion the family photograph we shared yesterday caused. I hope everyone celebrating had a very happy Mother’s Day.”

Shortly after the holiday of 2024, Kate revealed she was receiving treatment for cancer, contributing to her absence from the public eye. In September 2024, she announced that her chemotherapy had ended and, in January 2025, Kate revealed that she was in remission.

Kate’s focus on family life has remained clear even as she gradually returned to public duties amid her recovery. Throughout it all, sources close to the royal household say that maintaining a sense of normalcy for her children has remained a top priority for both Kate and William.

Despite their growing roles within the royal family, the couple are known for being hands-on parents — often doing school drop-offs and pickups at Lambrook School themselves and regularly appearing on the sidelines at their children’s sporting events and school activities.

Kate recently returned to public duties alongside Prince William, including a visit along the River Thames on March 12 where she even stepped behind the counter at a market stall to try her hand as a barista.

During the outing, she also shared a rare personal reflection on her health, revealing that she has been more mindful about alcohol consumption since her cancer diagnosis.

Looking ahead, Kate and William are set to return to a major royal stage in the coming week when they help King Charles host the President of Nigeria for a state visit beginning March 18.
