It's been a busy year for the Royal family. Prince William and Duchess Kate welcomed a beautiful boy, George Alexander Louis, on July 22, 2013. He may one day be the King of England, but for now, he's a playful little prince.
Always the precocious youngster, Prince George has already begun walking. True of any future king, Prince William has described George as a big boy with a voice like a "lion's roar." George, often compared to Prince William's brother, Harry, is a "fighter" that has a tendency to wriggle about in his mother's arms when he'd like to explore. With a bit of help from his mother, he's now on two feet, and mobile as ever. The notoriously-private family will likely have a small party for their perfect prince, but the whole world will be celebrating with them!
