Kate Middleton and Prince William are doting, hands-on parents to their children, Prince George, Princess Charlotte and Prince Louis, and sometimes share updates about them to the public.

The Duke and Duchess of Cambridge welcomed their third bundle of joy in April 2018, and since then, the royal couple has said some cute things about Prince Louis. Here are some of Middleton's sweetest comments about her children.

In January, Middleton visited Victoria and Albert Museum in Dundee, Scotland, with Prince William. While there, the duchess interacted with the fans who gathered outside the museum and shared an update about her youngest child.

Photographer Mark Stewart, who was in the crowd that day, posted on Twitter that Duchess Kate said Prince Louis was a "fast crawler" nowadays. According to Stewart, Middleton also told them that "she would love to bring her children to the new V&A Museum."

Last month, Middleton paid a visit to Henry Fawcett Children’s Centre, where she interacted with kids and learned more about "the work being done by local organizations in Lambeth to support young children and their families."

While there, Middleton had a conversation with one of the mothers, Kriti, who was there with her son, Kameron, 9 months. The duchess shared that her youngest is now eager to stand up and loves to "bomb around" in his walker, Hello! reported.

"Louis just wants to pull himself up all the time,” she explained. “He has got these little walkers and is bombing around in them."

Kriti also dished on her chat with Middleton, telling Hello! that the duchess has been getting a workout following Prince Louis around. "She took one look at Kameron and said 'Oh he wants to go walkies.' Apparently, her son is cruising (when a child pulls themselves up and uses furniture to move about) and she said she was running after him all the time," she said.

Back in March, Middleton also shared a cute tidbit about her only daughter, Princess Charlotte, while she was in Northern Ireland with Prince William. During a walkabout, the duchess talked to one of the fans gathered, Laura-Ann, and her 2-year-old son, George.

Middleton reportedly told the adorable blond tot that she is a big fan of his name, saying, "What a cool name you've got. And you look very smart in your bow tie." 

When the Pretty Much Me blogger told Middleton that her older son, Bertie, is now 4 years old, the duchess gushed that he is almost the same age as "Lottie." This appears to be her nickname for Princess Charlotte, according to Harper's Bazaar.
