"I have a husband and children that I adore. I have a career that I really love. When I sit back and reflect, it's – wow!" Holmes, 28, says in the March issue of Harper's Bazaar.
"I am very grateful. Tom makes me feel like the most beautiful woman in the world and has since the day I met him. I love being with him. I love calling him husband."
For her photos in the magazine's spring fashion issue, Holmes was styled by her close pal, guest fashion editor Victoria Beckham.
"Victoria has a strong sense of style – she knew the pieces she wanted Katie to wear," Bazaar editor Glenda Bailey tells PEOPLE. "Katie's style is very easy, laid-back."
The same could be said of her pregnancy with her daughter Suri, now 9 months – she had no morning sickness and no cravings besides cupcakes. "I felt so proud to be having a baby and so excited," she tells Bazaar. "And I felt closer to other women – to my sisters, to my mom. I felt empowered, like, 'I've given birth. I did it! There's nothing I can't handle.' "
Motherhood, too, has been easy to handle. "I've really enjoyed this time that I have taken to be with Suri as well as the challenges of the first couple of months: feeding and pumping, learning to decipher what each cry means – is she hungry? Is she tired? Does she need a fresh diaper? – and figuring out how to really help her."
Asked if she wants more kids, Holmes smiles and says: "Definitely."

"I have a whole new set of responsibilities," she says. "My work is very important to me. My family is very important to me. When I go to work, it will be the right thing, worth my time and worth my time away from my family."
