The Duchess of Cambridge produced a treasured family photo when she joined a group of schoolchildren asked to take in an object that makes them happy.
Kate took the image used for her 2018 Christmas card, showing her with the Duke of Cambridge and their three children, Prince George, Princess Charlotte and Prince Louis.
As she presented the picture the duchess said: "My family makes me feel happy and we like playing outside together and spending lots of time together."
Kate joined the pupils during a visit to Lavender Primary School in Enfield, north London, to mark Children’s Mental Health Week.
The youngsters had been asked to share objects which represented something that made them feel good.
When Kate first arrived children had gathered outside the school building and sang songs to welcome her.
Later the duchess, who wore a dress by Eponine, will go to north-west London to learn how the school of award-winning Andria Zafirakou, named the world’s best teacher, is supporting the wellbeing of pupils and staff.
Ms Zafirakou was awarded a million dollars (£766,000) in prize money and the 2018 Varkey Foundation Global Teacher Prize, which recognises an individual who has made an outstanding contribution to the profession.
