Meghan Markle has said that the poem that runs through her bestselling children's book was inspired by watching her husband and their son, Archie, together.

The Duchess of Sussex has given her first interview since the bombshell chat with Oprah Winfrey and had claimed that The Bench is a "love story" which she has written for Archie.

She also revealed that she loves seeing Prince Harry rocking Archie to sleep in a chat with Samantha Balaban on her NPR Weekend radio show, The Weekend Edition, which was recorded before the birth of her daughter Lilibet on June 4.

Speaking about the reasons why she wrote the book, Meghan said: "I often find, and especially in this past year, I think so many of us realised how much happens in the quiet."

The Duchess continued: "In the story I am observing this love between my husband and our son and imagining what it would be as they have more shared moments as our son gets older.

"From scraping a knee to having a heart broken, whatever it is they always have this moment to reset at this bench and have this moment to bond.

"It was definitely moments like that, watching them from out of the window and watching [my husband] just, you know, rock him to sleep or carry him or, you know ... those lived experiences, from my observation, are the things that I infused in this poem."

Meghan added: "There are lots of little small moments like that that were personal memories or anecdotes that I wanted infused in there."

This included being inspired by Princess Diana as she said that she has included her favourite flower, as well as her beloved rescue chickens.

She said: There's his mum's favourite flower, forget-me-nots, which we wanted to work in there - there was a lot of special detail and love worked into the book."

Speaking about her chickens, Meghan said: "I needed my girls in there."

Meghan has hopes that the story will touch many around the world. She added: The book is an intimate, personal insight into her family life which she hopes will transcend other families across the globe.

"It's a love story. It's really just about growing with someone and having this deep connection and this trust so that, be at good times or bad, you know that you had this person.

"I really hope that people can see this as a love story that transcends the story of my family."
