Prince George is already taking on a protective big brother role with Princess Charlotte.

The Royal Family released new photos Saturday showing George, who will turn 2 next month, cuddling and doting on his new baby sister, who was born on May 2. The adorable snapshots were taken by none other than proud mom Kate Middleton.

The photoset features Prince George in tiny blue knee socks and looking more than ever like his father, Prince William.

Kensington Palace also posted the images on Twitter and Instagram. Check them out below - and try not to squeal too loudly!
