Princess Kate's secret code when George, Charlotte and Louis are 'crossing the line'

Princess Kate uses a "secret code" to make sure her children are behaving as well as possible at major events.

The three young royals, Prince George, Princess Charlotte, and Prince Louis are usually on their best behaviour when at royal events and in public. However, they are children at the end of the day, which means we do get to see their cheeky sides from time to time, especially Prince Louis who is known for his hilarious and playful behaviour.

An expert revealed that when Princess Kate feels the children's behaviour is crossing the line she will use a 'code' to give them a final warning. According to body language expert Judi James, in 2023 as the Wales family rode in a carriage at Trooping the Colour event, we witnessed the Princess using her secret tactic.

Judi James said: "Kate's firm but subtle signals ensure the children keep feeling enthusiastic and in Louis' case, excited.

"Talking to her children there were a couple of gestures of what looked like guidance about when to wave. There was also a spreading gesture of both hands that would normally mean quite a severe message of when to stop or what not to do, too.

"She also put her hands below public view in the carriage to mime that 'stop' or 'end' sign to them as though warning them where the boundaries were, and on the way back she was doing small reward nods and smiles for their good behaviour, to ensure they were enjoying the event too."

It is not only at public appearances that the children must behave, but Prince William and Princess Kate also have strict home rules for them. When one of the children is struggling with their emotions, the royal couple take them away for a "sofa chat."

Additionally, the royals have a "no shouting" rule, meaning they will never shout at the children when they are telling them off, and if one of the children raises their voice, they are removed from the situation.

A source has said that Princess Kate is "slightly stricter" than Prince William and added that the couple's nanny, Maria Teresa Turrion Borrallo, always makes her decision in agreement with the royals.

They said: "Maria is firm but she never acts unilaterally with the children on discipline. Kate and William, along with Maria, are strict with the children but have this magic ability to appear not to be.

"It is a military operation but you would never guess it because they work ferociously hard on their children's upbringing and making it seem relaxed and happy for the three of them. They are very good at listening to the children but being firm."
