Kate Middleton's 'absolutely off limits' rule for George, Charlotte and Louis in the house

Kate Middleton and Prince William have one important rule for their children while at home.

• Kate Middleton's 'absolutely off limits' rule for Prince George, Princess Charlotte and Prince Louis in their home has been revealed. 
• The Wales family reside at Adelaide Cottage in Windsor, having moved from Kensington Palace recently. 
• In other royal news, Kate Middleton has a new outfits 'rule' from the Palace amid 'frustration'.

Prince William and Kate Middleton are open about the fact they're keen to give Prince George, Princess Charlotte and Prince Louis a 'normal' life, and that includes the three kids following rules at home. 

And while Kate has admitted she often suffers with 'mom guilt', there's one rule she likes to keep in place within the Wales family household. 

A royal source told The Sun, "Shouting is absolutely ‘off limits’ for the children and any hint of shouting at each other is dealt with by removal."

But rather than sending them to the popular 'naughty step' that many parents have, the royal children are given some time to learn from their mistakes in a calmer scenario.

The source continued, "There’s no ’naughty step’ but there is a ‘chat sofa’. Things are explained and consequences outlined and they never shout at them."

The source added that when the Prince and Princess of Wales are away on royal engagements, the couple’s Norland nanny, Maria Borrallo, is in charge. 

"Maria is firm but she never acts unilaterally with the children on discipline," the insider told the publication.

"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."

When it comes to explaining to future King, Prince George, about how important he will be when it comes to the monarchy some day, Prince William previously explained that he will be told all about it when the time is right. 

"There'll be a time and a place to bring George up and understand how he fits in, in the world. We are very normal," the Prince of Wales once said.
