The royal parents welcomed Prince Louis into our world on April 23, and we've been waiting for pictures of him ever since. Kensington Palace finally released the royal baby's photogenic pictures and we can't stop saying, "aww."

Prince William and Kate Middleton celebrated the birth of their boy and commemorated Princess Charlotte's third birthday on May 3 by sharing two stunning photos.

The first photo of Prince Louis taking in his plush surroundings was taken on April 26, three days after his birth, by the Duchess of Cambridge. He already looks comfortable cradled inside his makeshift throne.

It's love at first sight.

And then the photo of Princess Charlotte giving her little brother a loving smooch made our hearts melt. It doesn't get any sweeter than this.

The unexpected release of early royal baby photos broke conventions. Typically, royal parents don't offer a glimpse of their newborn portraits until months later after birth.

Kensington Palace announced:

Their Royal Highnesses would like to thank members of the public for all of the kind messages they have received following the birth of Prince Louis, and for Princess Charlotte's third birthday.

Kate Middleton is an avid photographer and documented her royal children through their various first time experiences, including first birthdays and first days of school.

The photo of Charlotte kissing her new brother is an ongoing tradition in the royal family. Remember the adorable capture of Prince George kissing the then one-month-old Charlotte back in 2015?

Here's a reminder.

Prince Louis is the fifth in the line of succession to the British throne, and we can't wait to see more pictures of his firsts along the way.
