Meghan Markle and Prince Harry announced they welcomed their daughter, Lilibet Diana, on June 4.
However, they did not make a statement about the addition to their family until June 6.
The couple's decision to keep the birth of their little angel private is in contradiction to royal tradition.
When Meghan gave birth to her son, Archie, she did not make an announcement until two days later.
The name of the hospital was kept private,until it was revealed Meghan welcomed Archie at the Portland Hospital.
As seen in Kate Middleton's delivery, an announcement was made when she went into labour with all three of her kids, followed by another after the delivery.
