Royal baby fever is sweeping across Britain -- and the world -- once again, even if it isn't as intense as the first time Kate Middleton gave birth to Prince George.

"I think the build up is not gonna be anywhere near the same intensity as around Prince George -- when he was born," royal journalist Robert Jobson told ABC News.

One reason is Middleton has already given birth to the heir to the throne -- George is third in line -- which makes this second child the "spare."

But that could change if Middleton, who is waiting to find out the sex of the child, has a girl.

"If it's a little girl I think it'll be hugely interesting for the media because it's a whole new story," Jobson said.
