While George and Charlotte had their first taste of snow, William and Kate broke from the formality of the photocall and showed off their playful sides, giggling and throwing snowballs at each other.

Just before their Jeep drove off to begin the open-air tour at Kaziranga National Park, Kate protectively squeezed her husband's thigh and said: "We're all safe."

After William was caught out by one of the children during the match, while Kate managed to bat the first ball, the Duchess sweetly consoled her husband.

William and Kate had fun playing mother and father to the smallest animals in the group, two elephants and one rhino – and made sure they drank every drop of milk.

In September, the couple returned to Canada – the place they first visited five years ago as newlyweds. This time William and Kate travelled to Yukon and British Columbia with their adorable children George and Charlotte.
Looking at the photos, the pair could still pass as newlyweds, laughing and sharing sweet looks of love...

The Duke and Duchess, in a red Caroline Herrera coat and heels, sat down on a log to join the schoolchildren. The book opens with a character called William the Moose, which prompted William and Kate to burst out laughing.

"Over the years William has looked after me, he's very supportive of me in the good times and the bad," Kate has said in the past.

Proving that they are one incredible A-team, William and Kate took charge of each of their kids, while also making sure they enjoyed the moment themselves.
The Cambridges looked like any other family, playing with balloons, running around the petting zoo and George gently teased his younger sister, squirting her with a water gun.
