Perhaps they are missing their own children but whatever the reason the Duke and Duchess of Cambridge were entranced by the energetic dancing of a three-year-old boy at a fireside festival - and laughed heartily when he cheekily attempted to stamp on their feet.
The couple smiled and pointed at him as he moved between a group of dancers and drummers including his father.
And Kate roared out loud when, after finally being introduced to the energetic youngster, he cheekily stamped on her foot.
The couple were beginning the third leg of their India visit at a Bihu festival by the Diphlu River Lodge in the Kaziranga National Park in Assam on Tuesday evening.
The Rongali Bihu - of Bihu of Happiness - is a spring festival marking the end of harvest and the beginning of the new year on Wednesday.
The couple arrived after a morning visit to New Delhi by private jet and after quickly freshening up, Kate changed into her third outfit of the day: an £805 (Sh116,000) green patterned ethnic-style dress by American designer Anna Sui.
