Elizabeth Notugu added: “Kate doesn’t tolerate nonsense from her children and sets rules, chores, and tasks to ensure they grow up with morals and an appreciation for hard work so, in that respect, she is like her mother-in-law.”
As a tight-knit family unit, the Cambridges have been open in the past about striving to provide a “normal” life for their three children.
Prince George is currently unaware that he is third in line to the throne, behind his father Prince William and grandfather Prince Charles, 71.
William explained to the BBC in 2016 why he wanted to protect his son from the revelation: “I love my children in the same way any father does, and I hope George loves me the same any son does to his father. We are very normal in that sense.
“There’ll be a time and a place to bring George up and understand how he fits in, in the world. But right now it’s just a case of keeping a secure, stable environment around him and showing as much love as I can as a father.”
