Prince William and Kate Middleton should take responsibility for their children, according to one former palace employee.

In August 2015, the Duke and Duchess of Cambridge issued a statement via their private secretary Jason Knauf regarding the "dangerous" and "distressing" ways the paparazzi used to take shots of Prince George and Princess Charlotte. "No parent would tolerate the suspicion of someone pursuing and harassing their child and carer whilst their child is playing in a public park or going about their daily activities," the palace said in a statement.

The photographers reportedly hid in the private fields and woodlands and used other children to lure Prince George into sight. They also monitored Prince Charlotte's movement who was just a baby at the time.

However, Princess Diana's former bodyguard Ken Wharfe recently said he believes that it would not have happened in the first place if the kids were not out in public. "My argument, having worked in similar circumstances, is if you don't want that intrusion, if you don't want that negative publicity, why do you need to take a baby that doesn't know where she is to a park in South London that's open to the public?" Wharfe said on Yahoo UK's "The Royal Box."

"They are in such a privileged position that that baby could have walked round the gardens at Buckingham Palace, Windsor castle, anywhere else in the world, without that intrusion," he added. "I think one has to be careful there."

Prince William and Middleton are keen to give their children a normal childhood that's why they are very strict when it comes to their children's privacy. In fact, when they were still living at Anmer Hall, the Duke and Duchess of Cambridge implemented a "no-fly zone" around their estate.

They did it to prevent helicopters and drones from taking photos of their children. When the family moved to Kensington Palace, Prince William and Middleton also planted 40-foot hedges so their kids won't be seen from the gates when they play outside.

In related news, Prince William and Middleton reportedly share photos of their children to the public from time to time to compromise. The royals believe that it was what's expected of them and they were hoping that the people would also give them some private time in return.

"Nothing is a given, but in terms of managing to keep a good relationship with the British media, it's in William's and Kate's interest to release photos," royal commentator Victoria Arbiter said.
