You have to be pretty special to have Oprah Winfrey curate a book club just for you. It would seem that Archie Mountbatten-Windsor, the young son of Prince Harry and Meghan, Duchess of Sussex, qualifies.

On Wednesday, the charity Save the Children U.K. posted a video on Instagram featuring Meghan reading Amy Krouse Rosenthal and Tom Lichtenheld’s Duck! Rabbit! to her son on his first birthday.

Some viewers of the video noticed that the book bore a sticker reading “Archie’s Book Club,” that looked a lot like the sticker for Winfrey’s famous club. That wasn’t a coincidence.

In a story in O, the Oprah Magazine, Winfrey confirmed that the book was one of many she sent to Archie before he was even born. “I don’t know the baby’s name or the baby’s gender, but this baby will have enough books to last a lifetime!” she had told Access Hollywood last year.

Rosenthal’s widower, Jason Rosenthal (author of the new My Wife Said You May Want to Marry Me), thanked Meghan for reading his book to her son, Us Weekly reports.

“Although Meghan Markle is clearly one of the most famous people in the world, seeing her read Duck! Rabbit! to her son Archie was so relatable to any parent anywhere,” Rosenthal said. “There he was squirming around, smiling and just being a regular little boy. What a testament to Amy that her book has such meaning to so many families.”
