Prince William and Kate Middleton have released six intimate photographs of their first vacation in the French Alps as a family of four.

The Duke and Duchess of Cambridge are pictured with a bundled up Prince George, 2, and 10-month-old Princess Charlotte, who's sporting two bottom teeth in a picture with her doting dad.

"This was ... the first time either of the children have played in the snow," Kensington Palace wrote in a Facebook post on Monday.

"It was very special and a fun short holiday for the family."

The royal couple invited Press Association photographer John Stillwell to capture the trip.

He managed to snap a few candid shots of the couple goofing around in the snow.

The two are both known to be fond of ski trips. It looks like it's a tradition the kids have happily embraced, even if they might be a little young for the slopes.
