Firstborn
This means that the heir’s firstborn child could inherit the throne regardless of their gender, so a younger boy in the line of succession no longer comes before an older girl. As you can tell, gender equality has joined the mix.
Their Baby
Harry and Meghan have also opted not to accept potential royal titles for their son. They wanted to wait until he is not a baby anymore. Archie could have gotten the title Earl of Dumbarton, a title which Harry has in Scotland. In the meantime, he will simply be referred to as “Master Archie”. However, this may all change after the Queen’s passing since it would mean everybody will move up the succession. Charles will take over the throne, while William will be the heir apparent.
