At the annual Trooping the Colour event,Prince William and Kate Middleton's two children nabbed plenty of attention during their first appearance together on the balcony of Buckingham Palace. The tiny princess waved and squinted as she looked up at the sky to see the Royal Air Force's flypast.

Tiny Charlotte was as chic as babies come in her ivory christening gown.

At dad Prince William's polo match at the Beaufort Polo Club in Tetbury, England, Prince George had a blast playing and dancing with mom Kate Middleton on the sidelines.  

While at the Sensational Butterflies exhibit at London's Natural History Museum, Kate and Prince George couldn't keep their eyes off of the beautiful insects.

Dad may have been playing on the field during the Jerudong Polo Trophy match, but Prince George wasn't far behind! In the safety of his mother's grasp, Prince George showed off his crawling skills.

George is becoming quite the baby trendsetter. How cute is he in his little red cardigan and gingham shorts?

He's a natural! Prince George shakes the hand of one of his many admirers.

It looks like Prince George already has the hang of the official royal wave!

Let's all say it together: "Aww!" In this official family portrait, shot by Jason Bell, the young royal family poses in one of the windows at Kensington Palace.
