Inside Prince William, Kate Middleton's effort to preserve Louis 'spirit'

Prince William and Kate Middleton treat their youngest child different than the elder ones.

The Prince and Princess of Wales are easy on Prince Louis, more than Prince George and Princess Charlotte, are just like ordinary parents.

A source tells OK! Magazine: "William and Kate are easier on Louis because he's the baby of the family."

"They don't want to break his little spirit," the source added. "William and Kate do their best to teach him how to behave, but understand these events are tiresome for a youngster."

This comes as insider previously told the Daily Mail of the family: "I think it would surprise people to see how ordinary things are at home. The children help with laying the table, clearing their plates when they've finished eating and helping with tidying up. There’s no preferential treatment."

Speaking about Prince Louis, royal expert Tom Quinn noted: "When Prince Louis misbehaved at the late Queen's Platinum Jubilee for example, by sticking his tongue out at his mother, Kate's reaction was praised by a team of expert commentators. She apparently used a secret code to calm the children , as she does on occasions - she simply says 'let's take a break'. But as a former staffer explained, the children know these few words carry far more weight than we might imagine."
