Hilary Duff models mint green on CBS Mornings while talking about her children’s book My Sweet Little Boy, which is about being both “gentle and strong”

Hilary Duff was in great form upon arrival on Tuesday CBS mornings in New York City.

The actress, 36, was there to promote her new book, My Little Sweet Boy, after writing My Little Brave Girl, a book dedicated to her daughters.

“Writing a boys’ book as a follow-up to my girls’ book seemed like the natural thing to do, the natural step to take, and actually it was a bit backwards because I had my son first, he’s 11,” she told host Gayle. King, Nate Burleson and Tony Dokoupi.

The best-selling author is mother to daughters Banks, five, and Mae, two, whom she shares with her husband Matthew Koma. She shares her son Luca with her ex-husband Mike Comrie.

And she also has a new home perfume line.

The How I Met Your Father star opted for a business-chic look, stepping out in a pale sage green blazer over a silver sweater and a silky silver maxi skirt.

She dressed up with a gold chain with several charms on it. Her shoulder-length blonde hair was styled in loose layers.

Hilary’s first book, My Little Brave Girl, was about her realization of the ways her daughter would need to be brave after her mother returned to work.

She said: ‘My first book was about going back to work and leaving my four-month-old son for the first time, and I only realized how brave she must be because it was so hard for me, and I thought, ‘She’s four months’. old and I’m all she knows.”

The author said writing her second book was a little more difficult.

“I felt like I went back so many years in remembering what my first experiences with motherhood and having this little boy were like,” she explained.

‘What was important for me to learn and teach him along the way, and my experience that he loved flowers and was very sensitive, and also loved breaking things.’

Publisher Penguin Random House described the picture book as “Inspiring young boys to be as gentle as they are strong.”

When asked why she wanted to add a page about the crying boy, Hilary replied, “I think there’s so much power in that, having access to your emotions.

“I know in my journey with him, with guys, it’s like, ‘Come on, be tough, stand up, you know you’re going to be okay,’” she explained.

“That was something I heard all the time and I thought, ‘What if he’s not doing well now?’ and “who am I to say he’s okay and tell him so at that moment?”

New from Hil: She also has a home perfume line that she announced on Monday

Explaining why it’s important for boys to explore their feelings, she said: “He’s going to learn how to control himself when he’s older, but why are we suppressing that now?”

In an Instagram Story video recorded in the green room, the younger star said, “I hope this book resonates with you if you’re a boy mom.”

After her interview was over, Hilary signed copies of her new book for fans waiting outside the studio.

My Little Sweet Boy was released on Tuesday.
