Jessica Alba: Two Kids Take Parenthood to ‘Another Level’

Pregnancy certainly hasn’t slowed this mom-to-be down! Between film promotions, starting a company, and being mom to 3-year-old daughter Honor Marie, Jessica Alba has been keeping busy.

“It’s a really exciting and fun time,” the Spy Kids 4: All the Time in the World star, 30, tells PEOPLE of expecting her second child.

“It feels like you’re really officially, really truly a mom when you have two kids. [With] one kid you’re a mom for sure, but two takes it to another level.”

The actress has been getting the nursery ready, re-finishing second-hand furniture for the room. “I use stains and paints that are eco-friendly and safe,” she explains.

While her husband, Cash Warren may not share her passion for vintage furniture and the work that comes along with it, he is happy to pitch in where needed. “He’s been very agreeable since I’ve been pregnant,” she says with a grin.

Alba has also devoted much of her time to The Honest Company, an ecommerce eco-friendly baby brand — named for her daughter — which will launch in the coming months. “Hopefully other parents love it as much as I do. I put my heart into it,” she says of the start-up.

But don’t count this entrepreneurial mommy out of acting.

“Doing the Spy Kids movie I got a taste of doing action again,” the former Dark Angel star says. “I liked it and I miss it … I’m really looking forward to finding a good action project. I was trained for so long on doing my own stunts.”

As for adding to their growing family in the future?

“I just turned 30. It’s hard to tell what will happen,” she says. “But I’m set for now.” (PEOPLE)
