The royal record-breaker
On April 23, 2018, Kate Middleton, the Duchess of Cambridge, gave birth to the third Cambridge baby at the Lindo Wing of St. Mary’s Hospital in London. On April 27, Prince William and Kate announced they would name their child Louis Arthur Charles. The fifth in line to the throne, he broke this royal record the day he was born.

The royal baby’s birth on paper
All births in England, Wales, and Northern Ireland must be registered within 42 days of the child being born, and that’s true for members of the royal family as well. According to the official website of the royal family, Prince Louis’s birth was registered at Kensington Palace on May 1, 2018, and was witnessed by a Registrar from the Westminster Register Office.
