Kate Middleton and Prince William’s attempt at giving their kids a normal life is just a “fantasy.”

The Duke and Duchess of Cambridge are keen on giving their three children Prince George, Princess Charlotte and Prince Louis a normal childhood. Prince William revealed earlier that they haven’t told Prince George about his future role yet. According to the second in line to the throne, they don’t feel that it’s time yet.

“There’ll be a time and 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,” Prince William told the BBC.

However, according to royal author Ingrid Seward, what Prince William and Middleton want for their kids is simply an unrealizable “fantasy.”

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

Although it would be difficult for Prince William and Middleton to achieve this, based on Seward’s revelation a lot has changed when it comes to the royal household and how they manage their kids.

The Duke and Duchess of Cambridge are very hands-on when it comes to their kids. They have a nanny but they still do things for their children. For instance, they drop and fetch their kids to school. They also travel with them.

In the 1960s, it was a “nanny-dominated world.” Royals also don’t travel with kids until after Princess Diana insisted to bring Prince William to a tour in Australia.

“Diana said, ‘he goes or I don’t go’, that was pretty much an ultimatum to the Palace,” royal photographer Arthur Edwards revealed how Princess Diana convinced Prince Charles to take Prince William with them to their trip.

“As they got off the plane at Alice Springs, the nanny brought William down from the plane and we are photographing him like mad, then, of course, Diana and Charles held him.” Kate Middleton, Princess Charlotte, Prince George, Prince William Kate Middleton organized a swimming race for her children Prince George and Princess Charlotte during their half-term break.
