Prince William, Princess Kate make Prince Louis's birth official

Prince Louis Arthur Charles was born at 11:01 a.m, local time on April 23.

“The Duke and Duchess of Cambridge have formally registered the birth of Prince Louis,” Kensington Palace said in a statement. “The Duke of Cambridge signed the birth register at Kensington Palace this morning, witnessed by a Registrar from Westminster Register Office.”

Prince Louis Arthur Charles was born at 11:01 a.m., local time on April 23.

The baby, known as His Royal Highness Prince Louis of Cambridge, made his first public appearance just seven hours after his birth outside St. Mary’s Hospital in London.

William, 35, and Kate, 36, traveled from the hospital to Kensington Palace, where they have been bonding as a family of five, including all three children: Newborn Louis, George, 4, and Charlotte, who turns 3 on Wednesday.

Kate will take some time off from official royal engagements, as she did after the births of George and Charlotte.

William, the Duke of Cambridge, is currently taking some time off to spend with his family following Louis's birth. He has attended two royal engagements since the birth. But, as a father actively engaged in the upbringing of his children, he is hoping to enjoy the precious moments of joy after the birth of a new child.

The family may then decamp to Anmer Hall -- their 10-bedroom home on the queen’s Sandringham Estate in Norfolk, England -- for added privacy.
