One year into motherhood, Hilary Duff is starting to learn the ropes of parenting.
And it's not all fun and games, especially when you live in Hollywood and have photographers trailing you and your child every time you step outside of the house.
"It's hard having a baby and having paparazzi follow you all around all the time," she explains in a new interview with "omg! Insider," airing Thursday.
"I haven't had to explain it to my son yet, what's going on. For the most part they respect me and they respect my space, but it's tough to always be photographed."
Along with the paparazzi, Duff is also navigating being a mom for the first time, to her son Luca. His dad is Duff's hockey player hubby, Mike Comrie.
"I'm at a really fun stage right now," she says. "My son is 13 months, so we just celebrated his first birthday. He's running around everywhere. He knows what he wants and what he doesn't like and really has a personality now."
Still, Duff admits there's a bit of a learning curve to being a first-time mother, and that it's important for her to take time for herself.
"It's kind of a heaviness at first, when to admit you just need to get away for a second, that's one thing I learned that is OK."
That includes time for exercise. Duff, 25, says it was a struggle to lose the 50 pounds she gained while pregnant with her son. But eventually she accomplished her goal by revamping her diet and hiring a trainer. Her Instagram page is filled with shots of her being active, including pics of her hiking canyons in L.A. with Luca, and doing wind sprints in her driveway with her trainer.
Duff recently chatted with omg! about her appearance on the season finale of "Two and a Half Men," as a woman trying to get the attention of Ashton Kutcher's character, Walden. She explained that filming worked well with her mom schedule. "I would get to go be with my son at the park and be finished by three o'clock in the afternoon," she said of the convenient gig.
And as if she didn't have enough on her plate, the third book in her "Elixir" series, "True," was released just last month.
She also might be interested in getting back into again soon, telling omg! last month, "I'm starting to get back into the studio again — I want to work on my music, but it's tough to be pulled away from Luca. Whatever I work on, I want it to be worth missing time with him."
Duff's also spending some of her time off partnering with Johnson's Baby Cares to deliver positive messages to deserving mothers with Johnson's Baby "Care Cards."
"It's all about giving moms the reassurance and the support and the confidence that they need."
