Praises have always flown for Kate Middleton. Aside from fans and supporters, she, also, receives compliments from several royal commentators and experts.

Recently, another set of commendations emerged for the Duchess of Cambridge. This comes as her birthday is fastly approaching, marking a new milestone in her life.

Speaking to People, a royal insider deemed her "flourishing" as she nears her 40th year. She has reportedly "really come into her own," adding that she is "more and more impressive as time goes on."

The source, who is said to be close to the Cambridge Royals, continued that the future Queen Consort is a "focused and professional woman." Not only has she stepped up in her role as a senior working royal, she has, also, maintained her strong links to her family.

As explained, the Duchess of Cambridge continues to "run things at home with the kids," as well as the schedules. She reportedly remains "hugely involved in every single part of their day."

For her upcoming 40th birthday, though, the Royals have yet to disclose any information about the celebration. So, whether it will be a grand or low-key event, that remains to be seen in the next few weeks.

Kate Middleton previously spent her birthdays at Anmer Hall, and often with Carole and Michael Middleton. Although she celebrated her 39th year at the same venue, she did not get to see her parents due to the COVID-19 pandemic.

In 2020, the Duchess of Cambridge marked the occasion with a "fittingly low-key celebration," according to Vanity Fair. The royal's friends had previously claimed that she would enjoy the weekend with Prince William and their three children.

The sources, also, shared that the future Queen Consort was not one for extravagant parties. The perfect way for her to celebrate her birthday would reportedly include a quiet tea and home-baked cake.

Meanwhile, Marie Claire recently stated that Kate Middleton and Prince William are "looking forward to starting fresh" in 2022. This comes as sources asserted that the couple is already thinking ahead to the new year.

The unnamed insiders added that the public will see a "transition of responsibility" from other royals to the Cambridge couple. They are reportedly taking on more charity work, alongside the additional engagements and appearances.

A royal tour is said to be "in the works," as well. Moreover, they are "heavily involved" in the Platinum Jubilee of Queen Elizabeth II, the source noted.
