Ahead of the twentieth anniversary of Princess Diana’s death and the release of the long-awaited documentary about her life as a royal, the princess’s two sons, Prince William and Prince Harry, shared private family snapshots from their childhood.

On Sunday, Kensington Palace released three throwback photos of the royal family on Twitter, captioning the heartwarming shots simply: “The Duke and Prince Harry are pleased to share 3 photographs from the personal photo album of the late Diana, Princess of Wales.” 

While all the photographs highlight different memories, they all encapsulate Princess Diana’s love and devotion for her only children. One adorable shot shows Diana’s arms wrapped around a young Prince Harry, who can’t help but grin from ear to ear as he holds onto his mother’s embrace. In another photo, which features the mom of two in a pink crew neck sweatshirt, and carrying Prince William as a tot, Diana was pregnant with Harry. 

“Believe it or not, we’re both in this picture, you’re in the tummy,” William said to his younger brother during a candid interview in Diana, Our Mother: Her Life and Legacy, according to BuzzFeed.
