If Kate Middleton and Prince William have a daughter as their first child, she will be next in line for the throne even if a boy follows, according to new rules.
That would not be the case as of this moment.
With The Duke and Duchess of Cambridge in the loop, plans are afoot by Prime Minister David Cameron's government to change existing ascension policy.
As current English royal law stands, if William and Kate's first child is a daughter but their second is a son, the boy would henceforth inherit the throne.
Cameron and other UK leaders are hoping to change this and several other ancient rules in order to bring the monarchy up to date with modern times.
He has already written the governments in the Commonwealth of countries ruled by the monarchy. The rule change will have to be ratified by all 16.
"We espouse gender equality, so it is an anomaly that in rules relating to the highest public office, we continue to enshrine male superiority," Cameron said.
The current Queen, Elizabeth II, is an anomaly herself, as only the second woman to hold the throne in the last 400 years. That's right, 400.
Her father, George VI, took over when Edward VIII abdicated to marry a divorcee, and had only two daughters, Elizabeth and younger sister Margaret.
If William were to similarly give up his status or die (heaven forbid) without having any children, Prince Harry would be next in line, not Kate Middleton.
