The royal mother-of-three, who shares her children Prince George, Princess Charlotte and Prince Louis with her husband Prince William, reads The Owl Who Was Afraid Of The Dark by Jill Tomlinson in the popular TV segment.
WATCH: First look at Duchess Kate on CBeebies Bedtime Stories!
In the first clip from the show, Kate encourages young viewers to 'face their fears' during her narration of the book to mark Children’s Mental Health Week.
The book tells the story of baby barn owl Plop, who is helped by others to grow in confidence and overcome his fears.

Kate says: "Wow, what an encouraging tale.
"We can all feel scared sometimes just like our little owl friend Plop, but as Mrs Barn Own said, 'It’s better to find out about the things that scare us before we make up our mind'.
"And with the help of others, we can often face things that worry us. Now it’s time for bed. Night night and sleep tight."
It's likely that the Duchess teaches her three children the same life lesson about facing things that worry them with the help of others – in George, Charlotte and Louis' case, help is most probably from their family, nanny and teachers.

Children’s Mental Health Week is a national event that has been taking place annually since 2015, when it was launched by the charity Place2Be, of which Kate is royal patron. The Duchess picked Tomlinson's book as the story fits well with this year’s theme of Growing Together.
Within the theme, adults and children are being encouraged to consider how they have grown emotionally, how trying new things can help people move beyond their comfort zones and how challenges and setbacks can help them to mature and adapt.
We can't wait to tune in to see the Duchess on CBeebies on Sunday. We bet her children will be watching too!
