Prince and Princess of Wales, Duke and Duchess of Sussex visited mourners at Windsor Castle.
During their visit, Princess of Wales told a group of children what her youngest child, Prince Louis, 4 said following the loss of Queen Elizabeth.
Banita Ranow, a well-wisher who was also at Windsor Castle said that she saw Kate interacting with a group of children.
"Louis said at least Grannie is with great grandpa now" Kate told the children.
In the video that has been going viral online, it can be seen Princess of Wale's interaction with the mourners.
By watching the video, it almost sounds like Prince Louis also told Kate not to worry. "Mama, don't worry, she's now with great-grandpa" Kate says in the video.
Such a precious wee boy.
