The Cambridges have a difficult task of balancing the publics interest in their children, their desire to see and know about them, and giving their children private lives, free of intrusion.
One of the ways the Cambridges deal with this is to release photos of their children every few months. We also see George and Charlotte on the occasional official engagement.
Prince GeorgeSo far we have had 22 Official photos/appearances of Prince George. That averages to approximately 1 set of Official pictures/appearance every 1.7 months (as of last picture/appearance).
So far we have had 10 photos/appearances from Princess Charlotte. That averages to approximately 1 set of Official pictures/appearance every 1.6 months (as of last picture/appearance).
These list do not include paparazzi pics, polo matches, airports, in the back seat of car, etc.
