They say you always want what you can't have -- and the saying rings true even for Kate Middleton.

When Middleton married Prince William in 2011 she was thrust into a lifestyle unlike any other. The media and people all over the world have become obsessed with her every move, and while it's surely annoying at times, it's a life that she chose. Her children -- Prince George, 6, Princess Charlotte, 4, and Prince Louis, 1 -- however, don't exactly have that same choice.

The royal children were born into this crazy lifestyle, but if it were up to the Duchess of Cambridge, they'd grow-up like their mother.

"She wants to emulate her upbringing, living in the countryside with a close-knit family," a friend of the royal told People in this week’s cover story. "She desperately wants that normality for her own kids."

Prince William apparently wants the same for his three children, but royal author Ingrid Seward believes that their attempt is just a "fantasy."

“Even the Queen in the ’50s said she wanted her children brought up as normally as possible,” Seward shared. “But it’s a fantasy [to say that].”
