Like most youngest children, Prince William and Princess Kate are more at ease with Prince Louis because he is the baby of the family, OK reports. Prince Louis is the third youngest child of the Prince and Princess of Wales, following his older brother Prince George, who is also heir to the throne, and his older sister Princess Charlotte.

"According to insiders close to the royal family, Prince William and Kate Middleton are playing favorites when it comes to raising the 5-year-old and his siblings, Prince George and Princess Charlotte," the outlet reported.

"William and Kate are easy on Louis because he is the baby of the family," the source said. 'They don't want to break his little spirit. (Please don't ever do that. The world needs Louis.")

Louis stole the hearts of the world at last year's Platinum Jubilee with his antics honoring the record-breaking 70-year reign of the late King. He continued to bring joy to the world with his coronation, Trooping the Colors, and the first royal event he recently experienced.

"Louis is quite a handful," says a source. 'William and Kate are doing their best to teach him some manners, but we understand that these events can be tiresome for a young child.' (See, sorry, the coronation was great, but it was also a bit long for this 36-year-old, let alone a 5-year-old.)

And Louis' antics in public make William and Kate more grounded and like us, the insider says: "In this respect they are just like any other parents with young children," the source said, referring to Louis' outbursts. (It happens to the best of us.

Thankfully, William and Kate have George and Charlotte to tame Louis. 'George and Charlotte gently tell Louis off when he gets out of hand. William and Kate know that the day will come when making faces will no longer be "cute." We hope Louis outgrows it."

Well... Maybe not too soon.
