Prince William and Kate appeared tired, but happy to have a night off Reuters

Like any young parents with toddlers even Kate and William need the occasional night off from baby duty to spend some quality time together. The Duke and Duchess of Cambridge, who added to their growing family in May 2015 with the birth of their second child, Princess Charlotte, enjoyed a low-key date at their local.

The couple dressed casually for their outing to The Crown Inn at East Rodham. The pub is a 15-minute drive from their home in Anmer Hall, Norfolk.

A source said the couple looked tired but appeared to be enjoying each other's company. "They both looked a little tired but seemed to have a lovely time and left at about 10.30pm," said the source. The young royals, who reportedly wanted a quiet table were said to be "leaning into one another chatting away, laughing and joking."

While Prince William had a glass of white wine, Kate, who was wearing jeans, stuck to sparkling water. It's been a busy month for the royal couple, with The Duke of Cambridge returning to work as an East Anglian Air Ambulance pilot, while Kate also attended her first engagement as Honorary Air Commandant of the Air Cadets to mark the 75th anniversary year of the Air Training Corps.

Kate attended a thanksgiving service at the RAF church of St Clement Danes in central London and a reception where she told Cadet Warrant Officer Lucinda Conder that she has shown Prince George pictures of Spitfires, with the toddler said to be thrilled with flying.

Conder, 19, told Mail Online: "He is now obsessed with the air cadets and wants to join. We are going to have to push that one when he gets to 12." Kate takes the role over from the Duke of Edinburgh, who was involved in the organisation for more than 60 years.

The couple – who are juggling family life with royal duties – will be visiting India for the first time in April. No official itinerary has been released but they are expected to travel around the Asian subcontinent between 10 and 17 April. Princess Diana was famously photographed alone outside the Taj Mahal during the height of her marital troubles, which led to her subsequent split from Prince Charles.

It has been reported that the couple will not be taking their children to India with them. William and Kate are said to have been concerned that the tour would be too grueling for the toddlers, particularly on young Princess Charlotte. The children will remain in the UK with their nanny, Maria Borallo, and maternal grandparents, Michael and Carole Middleton.
