Kate Middleton read a bedtime story to the nation's children, which was aired on CBeebies on Sunday 13 February.
It marked the final day of Children's Mental Health Week - the initiative she launched in 2015.
The mother-of-three, who is a royal patron of mental health charity Place2Be and who launched the Royal Foundation Centre for Early Childhood in June 2021, is known for her efforts to raise awareness of children's early childhood experiences and development.

She's formerly given emotional, heartfelt and moving speeches around this subject matter - including the time she encouraged children to be open about their emotions and emphasised the importance of them being supported while doing so.
This time around, the 40-year-old duchess read much-loved book, The Owl Who Was Afraid of the Dark by Jill Tomlinson, aimed at helping children to overcome fear.
It was a book the duchess recalled reading as a little girl and it resonated with the event's 'growing together' theme.
Following the reading, which saw Middleton look typically composed, she received the Queen's seal of approval as Her Majesty's official Instagram account liked a post on the Cambridges' page in honour of her appearance on the children's channel.
Royal fans also shared their admiration for the duchess, with one sweetly writing: 'Diana was the people’s princess. You are the children’s princess! So proud of the work you and William are doing!' when comparing her to the late Princess of Wales.
Another wrote: 'I do think she is a wonderful role model for children everywhere.'
Echoing the other heartwarming comments, a different fan commented: 'Catherine is amazing,' accompanied by three heart emojis.
A nod to Middleton's natural ability to mesmerise an audience, one royal fan wrote: 'Her voice is perfect.'
This year's event, which focussed on motivating children and adults to reflect on their emotional development, while 'recognising that trying new things can help people move beyond their comfort zones', per The Times, saw Middleton address her childhood.
'Hello, my name is Catherine and tonight we’re in my bedtime story den. I've chosen a story which I remember reading as a little girl,' she said when introducing herself ahead of reading.
The book, illustrated by Paul Howard, depicts a baby barn owl named Plop who is afraid of the dark and insists on not going hunting with his parents, before learning, with the help of others, to combat his fears and gain confidence.
After reading the story, Middleton gushed: 'Wow, what an encouraging tale.'
She went on to say: 'We can all feel scared sometimes, just like our little owl friend, Plop. But, as Mrs Barn Owl 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.'
Middleton is also believed to like reading this book to her own children, eight-year-old Prince George, six-year-old Princess Charlotte and three-year-old Prince Louis, whom she shares with Prince William.
Middleton, who previously opened up to the BBC about the 'ups and downs' of parenting, specifically when it came to lockdown during the pandemic, also spoke of her amazement at how aware her children.
At the time, she said: 'Although you don't want to scare them and make it too overwhelming, I think it is appropriate to acknowledge it in simple and age-appropriate ways.'
Still, Middleton's awareness when it comes to children's experiences doesn't go unnoticed.
Ahead of her bedtime story reading, Director of BBC Children’s and Education Patricia Hidalgo Reina said: 'I couldn’t be more proud to have the duchess read a CBeebies Bedtime Story as we mark the 20th anniversary of our CBeebies and CBBC channels.
'It’s such a special and relevant tale and perfectly represents this year’s Children’s Mental Health Week theme. I can’t wait to see her deliver her own take on such a classic story and I’m sure our audience can’t either.'
