Prince William and Kate Middleton have ‘chat sofa’ rule for their kids as one ‘off limits’ behaviour is never allowed at home

Prince William and Kate Middleton have a rule in their home when it comes to their three children, particularly when it comes to discipline.

Don’t be fooled by their royal status - they’re parents too, and when they see behaviour that isn’t acceptable, they clamp down on it like anyone else would.

The Prince and Princess of Wales even created a rule known as the 'chat sofa' when they see the behaviour exhibited.

The pair have been raising their three children to be outstanding Royals and, Prince George, 11, Princess Charlotte, nine, and Prince Louis, six have been known to be very well behaved in the public eye.

But what about at home?

Apparently, the pair avoid using things like the naughty step approach, and some other traditional means for punishment.

The step is generally a practice which sees parents send their child to sit away from the family on their own so they can think about what they have done, and come back with an apology.

To be honest, it's not an effective measure and it's widely criticised as being a bad method if you want to help your kid learn from their mistakes.

Instead, many prefer to talk their child through their mistake and work through it together instead of isolating them.

For William and Kate, they too like to talk it out.

A source told Fabulous Magazine: "There’s no ’naughty step’ but there is a ‘chat sofa’."

They explained: "The naughty child is taken away from the scene of the row or disruption and talked to calmly by either Kate or William.

"Things are explained and consequences outlined and they never shout at them."

The source then added: "Shouting is absolutely ‘off limits’ for the children and any hint of shouting at each other is dealt with by removal."

The person then recalled that the couple’s nanny Maria Borrallo is in cahoots with the parents when it comes to any decision regarding the children.

They said: "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.

"Maria Teresa Turrion Borrallo was recruited from the Norland College in Bath in 2014 when Prince George was around eight months old, and she has been a fixture in the family ever since."

Royal commentator Pauline Maclaran believes that the nanny would have a 'strong influence' over the children, adding: "I think royal nannies play important roles in the lives of royal children. Apart from looking after their everyday needs and security, they can also offer a lot of support in developing the children’s cognitive and social skills."

Macalaran commented that Borrallo possibly could 'offer important emotional support that ensures strong bonds will remain even when the children are adults'.

Even though the pair have a nanny, they've notoriously been very capable parents who constantly lead by example when it comes to their kids, and exhibiting proper behaviour.

This rule they have is living proof of that.
