If you need something to go "aww" this weekend, Prince Louis is covering you.

On Friday night, Prince William and Kate Middleton attended the 4th annual "Together at Christmas" carol Service at Westminster Abbey, along with their 3 children, Prince George, 11, Princess Charlotte, and Prince Louis, 6.

The couple's youngest child had a particularly heartwarming moment when the family stopped to put a note on the "Tree of Kindness" installed outside Westminster Abbey for the event and the photographer was able to glimpse Louis's Tree of Kindness note, which contains a sweet message to his maternal grandparents, Catherine And michael middleton.

"Thanks Grandma and Grandpa for playing games with me," he wrote in a note.

Members of the Middleton family have always maintained an active role in Kate's life as well as in the lives of her children. As people have reported, the Princess of Wales' parents Carol, 69, and Michael, 75, attended the "Together at Christmas" carol service hosted by Kate, as did her siblings, James Middleton and Pippa Middleton.

Royal sources have always spoken high about the Middleton family's involvement in the lives of Kate and her children.

"Her parents are a persistent factor in the upbringing of grandchildren" and a source described as a "palace insider" told the report that Middleton "is a constant presence in the life of grandchildren and often has George, Charlotte and Louis for sleepover."

And reports of Middleton's practical approach to his role as a grandparent are not limited to anonymous royal sources. Carol was open for a long time about her desire to become a very practical grandmother.

"I want to run down a hill, climb a tree, and go through a tunnel in the playground. As far as I can, that's what I'm doing. I cook with them, dance with them, ride my bike," Carroll told Good Housekeeping in 2021.

Thanks to Louis' sweet "Tree of Kindness" note, "Play the game" can be officially added to the list of activities Carol and Michael Middleton plan during Grandparent/Grandson Bond time.

Also, thanks to Louis's note, we can officially say that Bond time has great significance for Welsh children.
