The 2022 Earthshot Prize awards may have been the main reason for Kate and Prince William’s Boston trip but it wasn’t the only event on their agenda. Between meeting the city’s mayor, going to a Boston Celtics game, and greeting President Joe Biden, the couple had plenty to do. Not to mention, Netflix unveiled the trailer for Prince Harry and Meghan Markle docuseries during the visit. 

One outing included a stop by Harvard for Kate. On Dec. 2, the day of the Earthshot Prize awards, she went to the school’s Center on the Developing Child. 

There she spoke with researchers about scientific advancements to better every child’s future. Kate, who launched the Royal Foundation Centre for Early Childhood in 2021, also took a few moments to greet well-wishers.

Almost six months exactly after a viral parenting moment with Prince Louis, 4, at Queen Elizabeth’s Platinum Jubilee festivities, Kate had yet another relatable parenting moment. Just as she was about to sign the guest book at Harvard, she joked about having to remember the date.  

“As a mother, you sort of have to work out which month or year you are in,” Kate said (via Express), which prompted smiles. 

On this particular overseas trip, William and Kate weren’t joined by their children. Instead, Prince George, 9, Princess Charlotte, 7, and Louis stayed home with their longtime nanny (via Hello!). 

That wasn’t the only memorable moment from Kate’s Harvard visit. She also learned King Charles had also signed his name in the guest book decades earlier. When it came to her attention that her father-in-law had done the same, Kate replied, “Amazing!”

Jack Shonkoff, director of the center, called the visit from Kate “remarkably relaxed and informative,” telling People “it was a lovely one hour that we spent with her.”
