Soon after, two year old Princess Charlotte melted hearts with her charismatic display of smiles and Royal waves as she totted up the steps to the Lindo Wing, alongside older brother Prince George and her father, Prince William.
History reveals we waited a lot longer to find out names of royal babies in the past, with Prince William's name not announced for a week, and Prince Charles's a whole month.
While handsome George arrived at the Lindo wing still wearing his school uniform, his younger sister wore an ADORABLE blue frock. The Duke and Duchess of Cambridge's kids accompanied their dad when Prince William visited Middleton. Overnight, as she revealed the newest addition to the Royal family, the Duchess wore the same designer and paralleled the red-dress-with-the-white-collar that Princess Diana wore when she exited the hospital with her son Harry.
Unlike Prince Harry and Royal-in-waiting Meghan Markle, we never see the Duke and Duchess of Cambridge cuddle up to one another.
Buffalo Bills draft capsule
Buffalo Bills fans are preparing for some big trades, but even if none go down the team still has two picks in the first round. If the Browns selected a quarterback with their first-round picks at No. 1 and No. 4, it would be unprecedented.
The line of succession falls next to William's eldest son, Prince George, who stands the most likely chance of actually becoming the monarch one day.
Prince George guided his little sister into the Lindo Wing by putting his hand on her shoulder as they walked down the corridor.
The Duck left the hospital, telling crowds, "I'll be back in a minute", before returning with George and Charlotte to introduce them to their new brother.
According to a royal photographer, an ideal photo when Middleton leaves the hospital after delivering the new baby would be capturing the family of five.
