In photos from the day, the 9-year-old appeared to cry, prompting his great aunt to comfort him as they attended the services alongside his father, Prince William, his mother, Kate Middleton, and his sister, Princess Charlotte. His little brother, Prince Louis, 4, did not make an appearance, as he is still too young to understand what is going on.
Despite the small fit of tears, Prince George and his 7-year-old sister were on their best behavior during the headline-making ceremony. "They looked like really incredibly well behaved kids but a little like kids, a little like, 'wow this is a lot,'" attendee Mark Tewksbury, a member of the Order of Canada, said of the siblings.
"For little Prince George, this will be him one day and he doesn't really know that yet. And then I thought, 'Ah, he's just lost his great-grandmother,'" he continued.
As OK! previously reported, the new Prince and Princess of Wales are trying to keep everything as normal as possible for their brood as they navigate this difficult time.
"He spoke about George, Charlotte and Louis, saying that they were trying to keep some sense of continuity for them at school and keep things as normal as possible," Elaine Gee, a local teacher, shared of a conservation she had with Prince William.
Both Prince George and Princess Charlotte trailed behind their great-grandmother's casket as it made it's way to Westminster Abbey in London. As the coffin passed the brother and sister duo, Prince Charlotte instructed her older sibling to bow in homage to the royal matriarch.
