Duchess Kate: "Don't tell the children"

During the interview with the BBC, Kate said: "Don't tell the children, we've actually kept it going through the holidays. I feel very mean." The couple also talked about their family life in times of the COVID-19 pandemic and William described homeschooling as "fun" while his wife added it was "challenging".
