Pictures of the latest addition to the United Kingdom's royal family are finally here, two days after the boy's birth.

The baby boy, the first child of Prince Harry and the duchess of Sussex, formerly the American actress Meghan Markle, is seventh in the line of succession to the throne. His name is Archie Harrison Mountbatten-Windsor, the couple announced on their Instagram account.

Posing with the new bundle of joy outside the hospital is a recent custom. The duke and duchess of Sussex declined to follow suit in order "to celebrate privately."

That doesn't mean the Windsors traditionally have kept their baby pictures secret.

From great-grandmother Queen Elizabeth II to cousins George, Charlotte and Louis, the world has seen photos of multiple generations of Archie's relatives during their early days of life.

The images also provide a fascinating look at how little infant clothing has changed over the past century or so: lots and lots of frills, ruffles and bonnets.

Chuckle at the cherubic cheeks, coo at the button noses and compare the royals to see which one was the cutest baby.

Even kings and queens have baby pictures. Queen Elizabeth II is shown here in 1926. She was born on April 21 of that year. PhotoQuest/Getty Images hide caption

Correction May 8, 2019

A previous caption on this story incorrectly said that Elizabeth II's husband, Phillip, did not have the title Duke of Edinburgh in 1950. He received that title when they were married in 1947. In addition, another caption called Prince Charles' then-wife, Diana, Duchess of Wales. Her title was Princess of Wales.
