The past year has been quite a joyous ride for the second in line to the throne. Just last month the doting dad made his way to St. Mary's Hospital to welcome his first daughter, Princess Charlotte of Cambridge, and has already proved that he can balance the additional responsibilities. He's been seen spending quality time with his firstborn son and the daddy-son duo were even spotted wearing matching outfits as they took Prince George's baby sister home for the first time to Kensington Palace. Although the last couple of months have been busy for the royal dad (and probably been without much shut-eye!), the dashing royal seems to have as much energy as his little ones and has returned back to work as an air ambulance pilot. He even showed off his athletic skills at the Audi Polo Challenge in support of some of his favorite charities.
