Prince Louis is set to celebrate a special occasion this week as he turns seven on Wednesday. Louis, the youngest child of Prince William and Princess Kate, is set to celebrate his birthday with his nearest and dearest. While he is still young, it is believed that the young prince’s birthday will prompt mixed emotions for Kate, 43, as he is the youngest of her three children and therefore still her “baby”.

The princess, who calls Louis “Lou-bugs”, has a soft spot for the young prince and is often seen trying to stifle laughter when he shows his fun mischievous personality at royal events. Talking about Louis’ position as the youngest in the family, former BBC royal correspondent Jennie Bond told The Mirror: “Being the youngest is often something of a privilege.

"You get away with a lot more and you are that little bit special as the lastborn.”

She continued: “Catherine probably lets Louis run wild more than she did with George. She and William are very experienced parents and I’m sure they love all three kids equally – but probably in different ways.

“George because he’s the firstborn and has a destiny to fulfil, Charlotte because she’s the only girl, and Louis because he’s the youngest.”

While Kate has not spoken about her feelings ahead of Louis’ seventh birthday, she did mention a few years ago that her youngest son seems to be growing quickly.

At a royal engagement at a maternity unit in Surrey years ago, Kate told some mothers: “I keep thinking Louis is a baby, but he’s a big boy now.”

Plans for the young royal’s birthday have not been publicly disclosed, however it is likely he will celebrate with his relatives.

It is also likely Kate will bake Louis a cake, with the princess having once spoken about how baking a cake for her children’s birthdays had become a tradition.

She told UK cooking icon Mary Berry in the 2019 BBC Christmas Special A Berry Royal Christmas: “I love making the cake. It's become a bit of a tradition that I stay up 'til midnight with ridiculous amounts of cake mix and icing and I make far too much. But I love it."

It is also likely that a picture of the prince will be released by Kensington Palace on his birthday to mark the special day.
