Model, actress and author Molly Sims is never too busy to spend time with her 2-year-old son Brooks. And life is about to get even more frenetic as Sims and husband Scott Stuber prepare for baby number two.

Making time

Five months pregnant, Sims says she’s battling some nauseous and fatigue, but that’s not slowing her down—even as she chases her toddler around. “I am still able to make one-on-one time with my son, and that's the most important thing to me,” says Sims, 41, who just spent the day with Brooks visiting a toy store followed by ice cream.

Although ice cream is a treat, Sims tries to eat healthy, especially organic and natural. “It’s so vital and important, even after nine months of being pregnant, to make sure the baby is getting the proper nutrients to be as healthy as possible,” she advises, adding she prefers small meals throughout the day.

Staying fit

A frequent Sports Illustrated Swimsuit model, Sims stays fit with daily activity. “With this pregnancy, I’ve been very into prenatal Pilates. I also go on walks and hikes, and of course, run around after Brooks,” she says.

“Your baby’s skin is the biggest organ and you need to be conscious of what you are putting on it, such as harmful chemicals.”

That keeps her in shape, even during pregnancy, for a sleek fitting wardrobe, which she believes is more flattering than looser clothing. “That actually makes people look larger,” she suggests. “My go to looks are bohemian skirts, cardigans, a boyfriend jacket with a fitted tank, and of course, every pregnant woman needs a great pair of leggings. My mom always said if you look good, you feel good and if you feel good, you look good.”

Gearing up for her the new baby, Sims lists good wipes, a comfortable swaddle, a swing, a great changing pad and a breast pump as essentials. “I love my glass bottles as well because we try to stay as ecofriendly as possible.” For baby’s skin, she says she always looks at the label. “Your baby’s skin is the biggest organ and you need to be conscious of what you are putting on it, such as harmful chemicals.”

A new baby isn’t the only addition for Sims, who has a new book and a makeup line coming out in January. In the meantime, she and Brooks often visit with film producer Stuber on the set of his newest addition, Ted 2. “Brooks has been traveling since he was 6 weeks old so he knows the drill and we love it. We try to keep him as occupied as we can bringing activities, sticker books, pipe cleaners, hot wheels cars and an iPad.” And like any new mom, Sims sets up play dates and takes Brooks to toddler programs. “I never knew what [it takes] a village meant until now,” she says.
