There's nothing sweeter than seeing grandparents bond with their grandchildren, and the same is true for royal families. Despite the formality of their events and engagements, there are snatched moments when we see royals display genuine affection for the tiniest members of their family.
In June at Trooping the Colour, the Duchess of Cornwall's eyes lit up when she spotted her grandchildren among the masses outside Buckingham Palace. Camilla, who was riding in a carriage with the Duchess of Cambridge, looked over and waved at her son Tom Parker Bowles and her grandchildren Freddy and Lola. Tom, his wife Sara and their two children were watching the Queen's birthday parade from the Mall.

Prince Charles became a grandfather for the first time in July 2013, following Prince George's birth. The future King has previously opened up about being a granddad, saying: "It's a different part of your life. The great thing is to encourage them. Show them things to take their interest. My grandmother did that, she was wonderful." He added: "It is very important to create a bond when they are very young."

Harry has previously opened up about his relationship with his grandmother. "I still view her more as the Queen than my grandmother," he said on BBC show, Elizabeth At 90 – A Family Tribute.
"You have this huge amount of respect for your boss and I always view her as my boss – but occasionally as a grandmother. "And the more grandmother bits, the more I can get advice and suck all that information out of her and all that experience that she's had for so long."
