Kate Middleton's House of Manners: Strict 'Household Rule' Prince George, Princess Charlotte and Prince Louis Must Follow in Wales Household

Kate, Princess of Wales, is a firm stickler for protocol in the Wales household, and this includes a "strict" rule for Prince George, 11, Princess Charlotte, 9 and Prince Louis, 6.

"Shouting is absolutely 'off limits' for the children and any hint of shouting at each other is dealt with by removal," a Wales estate insider revealed.

If any of the royal kids step out of line, spankings and such are forbidden, but Prince William and his future queen employ a more unique approach to discipline.

"The naughty child is taken away from the scene of the row or disruption and talked to calmly by either Kate or William," they added. "Things are explained and consequences outlined and they never shout at them."

The Prince and Princess of Wales have both made it a point to put their three children above everything else — including the Crown. This drastically differs from past royal generations, who lived by the mantra of "duty first." However, the next monarch and consort ensure that this extra attention does not lead to spoiling their children.

"They're raised with an understanding of royal procedures and protocols," Jo Frost of Supernanny told an outlet in February. "And they're raised to understand, there's a time and a place... They have a lovely balance of that and behind closed doors, no doubt they're playing games and winding each other up as siblings do, teasing each other, having fun and baking cookies and being out in nature."

This parental leadership is set to continue in the years to come according to another top analyst.

"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," veteran royal commentator Jennie Bond told an outlet in the spring of 2023. "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 concluded: "William benefitted greatly from the extra attention his mother, Diana, Princess of Wales, showed him as a kid. But even the late princess and King Charles III put their duties before their parenting. Catherine is determined to avoid this past hallmark of royal life as George, Charlotte, and Louis mature."

And Prince George, who turned 11 on Monday, July 22, could be the elder sibling who takes up these traits for his younger sister and brother.

"Kate's illness this year has obviously been distressing for George but as the eldest family member he is expected to set an example to his confident younger sister, Charlotte and little brother Louis and he has been especially protective," Majesty Magazine Editor-in-Chief Ingrid Seward shared.
