Prince Louis reportedly landed an adorable two-word nickname inspired by his name when he was born seven years ago. In his 2024 book about Princess Kate, titled ‘Catherine, the Princess of Wales: The Biography’, author Robert Jobson recounted the birth of Prince William and Kate’s youngest child in 2018.
The young prince, who turns seven on Wednesday, was born in a private wing of St Mary’s Hospital in London, where he was greeted by his big brother and sister, the future King George and Princess Charlotte. The Prince and Princess of Wales later introduced their son to the world, with William jokingly telling well-wishers that there was “thrice the worry now”. Meanwhile, the smitten siblings had given the newborn a cute nickname.
Robert wrote: “Catherine gave birth to her third child, a son they named Louis, on 23 April 2018, again at the private Lindo Wing of St Mary’s Hospital in Paddington.
“Before introducing him to the world, William had brought the baby’s older siblings, George and Charlotte, to meet him. They affectionately called him ‘Lou Lou’.”
It wouldn’t be the only nickname pinned to a royal that day, as the waiting media labelled the future Queen “super mum”. However, Robert said Kate felt “fragile” and was eager to leave quicker than on the last two occasions.
Their son was baptised Louis Arthur Charles on July 9th, 2018, at the Chapel Royal at St James’s Palace. King Charles III and Queen Camilla were in attendance, alongside the Duke and Duchess of Sussex and Princess Kate’s family.
On Monday, it was reported that the young prince’s birthday was generating mixed emotions in Kate, who, according to former BBC royal correspondent Jennie Bond, “probably lets Louis run wild more” than she did with George.
She told the Mirror: “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.”
The Princess of Wales, who now calls her youngest “Lou-bugs”, has been seen attempting to stop herself from laughing when Louis shows his mischievous side at the Royal Family’s events.
Kate previously shared insights into how she views her son. Speaking at a royal engagement at a maternity unit some years ago, she said: “I keep thinking Louis is a baby, but he’s a big boy now.”
Louis’s birthday plans haven’t been revealed to the public, but it’s thought that he will mark the day with his relatives. The Express also reports that Kate could make a cake, having once revealed that baking a cake for her children’s birthdays had become something of a tradition.
