How Kate Middleton pronounces her son Prince Louis' name

The Royal couple held hands as they walked down the steps of the hospital

Kensington Palace marked the occasion with an adorable throwback photo from the Duke and Duchess of Cambridge's wedding day in 2011.

Private schools, personal security and childcare are just some of the costs William and Kate will pay to raise Prince Louis.

"It completes them", royal biographer Ingrid Seward tells PEOPLE in this week's cover story. The vehicle is adorned with balloons, streamers and a license plate reading "JU5T Wednesday", with the number five cleverly taking the place of an "S".

The Prince of Wales, who grew up without grandfathers, referred to Lord Mountbatten as his honorary grandfather so the name will surely please him.

The first he heard of his noble namesake was when he arrived at work after the Duke and Duchess of Cambridge made the announcement.

The wedding attracted the same sort of public fervor as that of Lady Diana and Prince Charles's nuptials back in 1981.

'Colleagues kept saying, "Louis, you've got the same name as the royal baby!",' said the operating theatre assistant from Cheltenham.

Just like with all of Kate's pregnancies, news of the royal bundle joy's arrival was first shared by Kensington Palace with an official statement, which also listed a couple of details such as the boy's weight and time of birth.

On April 23 the family of Kate Middleton and Prince William was a joyful event - they became parents for the third time.

The 36-year-old Middleton has two siblings, so she's used to a big family and might be trying to recreate that same dynamic.

Parenthood, the friend added, "suits them really well".

Kate once said feisty Charlotte is "the one in charge" at home with older brother George. All because she's a girl.

So much will it cost to raise Prince Louis? "I was so chuffed to see the baby's name.' And the links extend to Louis" sculptor dad Chris, 57, who created a pedestal for a bronze bust of the Queen which sits in Westminster Palace.
