The 38-year-old royal - who has Prince George, seven, Princess Charlotte, five, and Prince Louis, two, with Prince William - made the quip while answering early-years questions from members of the public.

In a video posted on Instagram about her ongoing work on behalf of children and their parents, she said: "I just want to say a huge thank you to everyone who sent in their questions. There are a huge number here with loads of wonderful emojis attached to them."

As part of her work, the Duchess' office recently released the results of the UK's largest-ever study on early childhood development.

Asked what ignited her interest in the issue, the Duchess explained: "I think people assume that because I am a parent, that’s why I’ve taken an interest in the early years. I think this really is bigger than that.

"This isn’t just about happy, healthy children. This is about the society I hope we could and can become.

"Right from the early days, meeting lots of people who are suffering with addiction or poor mental health and hearing time and time again that their troubles now in adulthood stem right back from early childhood experience."

The Duchess - who has been married to Prince William since 2011 - was subsequently asked about the challenge of coping with toddler tantrums.

In response, she joked: "Yes, that’s a hard one. I’d also like to ask the experts myself!"

The Duchess also admitted that her recent work has only scratched the surface of the issue.

She said: "This really isn’t something that we are going to be able to change quickly and overnight. It’s going to take generations and I’m keen to support this for the long term."
