The royal couple have a lot to celebrate, welcoming their third child, Prince Louis who was born on April 23rd.

The little one is now home at Kensington Palace with his parents and big brother George and big sister Charlotte.

Ingrid Steward, a royal biographer told People, “It completes them.”

Prince William and Kate's cutest moments through the years:

William and Kate met back in college and wed seven years ago. Kate walked down the aisle of Westminster Abbey in an Alexander McQueen gown and married Prince William in what seemed like a fairytale wedding.

Their first child, Prince George, was born a year in a half into their marriage, and their daughter Princess Charlotte arrived two years later.

With the birth of a new brother a friend of the couple said:

“Kate’s worried that Charlotte will feel it the hardest as the youngest, but she’s such a confident little girl and growing up so fast, Kate is hoping she will adjust.”

Prince Louis is now the fifth in line for the throne.

Happy anniversary Kate and William!
