Why we just can’t wait to meet Royal baby number three!

The nation rejoiced yesterday with the exciting news that the Duke and Duchess of Cambridge will be welcoming their third child.  

With Kensington Palace confirming the upcoming royal birth, we look back at some of the happiest moments from the young royals’ lives so far. 

These pictures chart how Prince George has flourished from an adorable bundle tenderly held in his mother’s arms to a caring big brother for little sister Charlotte.

And the highlights of perfect Princess Charlotte’s life are remembered including her turn as a flower girl at Aunt Pippa’s wedding.
