How Prince William is making sure Prince George and Princess Charlotte have a normal childhood

While rumors spread that the royal family might be expanding, Vanity Fair has revealed the lengths to which Prince William has gone to preserve a sliver of normalcy for his children.

In the new Vanity Fair, Katie Nicholl writes that William and wife Kate Middleton's 13-month-old daughter, Princess Charlotte, lives a guarded life. In fact, William seems to have made a concerted effort to keep his children out of the spotlight since Charlotte was born.

The Duke and Duchess of Cambridge moved 100 miles from their official residence at Kensington Palace in London to secluded Anmer Hall in Norfolk just 48 hours after Charlotte was born.

Since then, there have only been rare glimpses of the baby princess. While Prince George, 2, stole the show during the family's tour of Australia and New Zealand in 2014, his sister Charlotte's only official appearance was at her christening last year.

Last month, official photos were tweeted in honor of Charlotte's first birthday, showing off the toddler's blue eyes and striking resemblance to her great-grandmother, the Queen.

Assisting with keeping the little tykes away from prying eyes is the bastion of security shielding Anmer Hall.

"If you happen to pull up outside, you're very quickly moved on by a patrolling police car," Nicholl told ET. "And earlier in the year, Prince William put up a no-fly zone."

Despite its outward appearance, within the fortress-like perimeter is a warm and welcoming home. According to Vanity Fair, Kate often cooks family dinners as they do not have a chef. Additionally, the parents reportedly take turns giving the kids baths and tucking them in at night.

While the family is enjoying their time in the countryside, royal insiders tell the magazine that the quaint lifestyle they've curated for themselves might not last. As the Queen delegates more duties to Prince William and Prince Harry, it might require William to move back to London. In the meantime, William is focused on raising his children in a normal environment away from paparazzi lenses.

"William doesn't want George and Charlotte going through some of the experiences he went through growing up," a source told Vanity Fair. "Everything he does regarding his family is very deliberate."
