Kate Middleton Steps Out Five Hours After Giving Birth, How Did She Do It?

Prince William and Duchess Catherine have given the world their very first glimpse of their third child, a darling baby boy - and he's already a record breaker!

The new Royal has tipped the scales at 3.8kgs - the biggest Royal male baby in 100 years!

This impressive number means the new Prince's newborn weight is heavier than any of his siblings.

Not long after the Prince's arrival was announced on the Kensington Palace Twitter account, an official notice was placed on an easel in the forecourt of Buckingham Palace to mark the birth of their third child.

"A notice has been placed on the forecourt of Buckingham Palace following the announcement of the birth of The Duke and Duchess of Cambridge's third child," Kensington Palace explained via Twitter.

"It is tradition that a framed notice of birth goes on display on a ceremonial easel on the forecourt at the Palace," the statement continued.

However, what we're more impressed by is how Kate managed to step out and greet the public just five hours after giving birth to her baby at the Lindo Win hospital.

Those after pains also get worse with each baby you birth.
