The couple were left red-faced when one royal fan asked about the chances of baby number four, sending social media into a frenzy over the footage.
A clip of the exchange began when a fan asks Kate whether she “wants to nurse” as she offers to hand the royal a baby.
Kate immediately smiles at William and responds: “I would love it!”
William adds: “More and more babies, she loves to cuddle.”
When Kate tells the baby he is “so sweet,” William agrees: “He is very, very sweet.”
The Prince and Princess of Wales were caught off-guard by the blunt remark
Many viewers joked that William appeared more reluctant than Kate when it came to the question
At this point, one royal fan pops the question and asks: “Are you going to try tonight?”
Both William and Kate immediately laugh at the question.
The Prince of Wales seems to respond: “Yes exactly, that’s how it ends.”
One royal fan account on Twitter @cambridgepower called it “one of the best moments of the visit to Northern Ireland today”.
Many viewers joked that William appeared more reluctant than Kate when it came to the question of another baby.

@LadyF83431206 posted: “William is like, ‘Oh god, not this again? Kate! Step away from the baby!'”
@Royals_borough added: “William’s face. I can’t.”
The responses echo the Princess of Wales, who once admitted that William “worries” about her meeting babies in case it leads to plans for baby number four.
During a trip to Denmark in February this year, her first solo royal tour, Kate met with parents and their babies during a visit to the University of Copenhagen.
The incredible exchange, which was later shared online, took place after Kate held a baby
At the time, she said: “It makes me very broody. William always worries about me meeting under 1-year-olds.
“I come home saying, ‘Let’s have another one.’ ”
Earlier this week, during a visit to Royal Surrey County Hospital on Wednesday, the Princess of Wales recalled that “it feels like yesterday” when Prince Louis was a baby.
She told one mum: “I keep thinking Louis is a baby, but he’s a big boy now. It just feels like yesterday.”
