Princess Kate's 'radical new methods' added into Royal Family upbringing

Jennie Bond explained how this “radical new way of parenting” is “about exploring the child’s own feelings, confusions and anguish” and “allowing them to lead the way”.

"It is about letting them express those emotions and sitting down to discuss them with the child, rather than ignoring the turmoil that growing up so often involves,” she told OK!.

“It is fantastic and I believe Catherine will very much be the leader in this and William will be the follower, he will have been learning from Catherine how to be a different kind of parent.”

Bond said this style of parenting is “all about positivity” and encourages children to become “rounded young people”.

“The other important word is preventative, which Kate has used a lot, and she believes in so strongly,” she continued, expressing an aim to try and “prevent so much mental anguish turmoil or addictive habits or various troubles that might come along in adulthood”.

The royal journalist also reiterated that she believes Prince George, Princess Charlotte and Prince Louis are being raised with “mutual respect, good manners” with Kate and William “explaining why good manners are important and that kindness begets kindness and that inclusivity should be natural”.

"But perhaps most importantly giving her children all of the time that she can,” Jennie added.

“We're all pressed, we're all rushing, and she has a huge job, but she gives them as much time as she can to sit down with them, discuss their problems and play with them and just be with them."

King Charles is keen to help his grandchildren avoid the mistakes he made, according to a royal historian.

The King has a close relationship with Prince William and Princess Kate's three children George, Charlotte and Louis.

Professor Chandrika Kaul told Channel 5's documentary The Fab Five: The King's Children that Charles wants his grandchildren to grow up in "as normal a way as possible".

Kaul said: "I think King Charles is very keen that his grandchildren don’t make the mistakes that I think he feels he made, particularly."

The historian continued: "What I think he wants to do is try and help these young grandchildren grow up in as normal a way as possible and create more fully rounded human beings who are unafraid of their emotions."
