There's a rich irony to an oil heiress deciding to go green. And Anna Getty is well aware of that: "I know our background is in oil, but everyone in my family drives a hybrid now," says Getty, 35, as she laughs and nibbles a croissant at a café near her Los Angeles home. "For me, becoming a mom was the catalyst for getting into this way of life. It changed everything."

Motherhood not only gave impetus to Getty's eco-epiphany—it also became her new career focus. Since giving birth to India (now 3), the longtime yoga instructor has homed in on fitness for moms, recently debuting a DVD box set, Anna Getty's Pre & Post Natal Yoga Workout. This month, she's launching Pregnancy Awareness Month (PAM), an effort to empower and educate expectant mothers. "When I was pregnant, people kept telling me that it was going to get horrible, and luckily it never did," she says. "I know that's not the case for everyone, but I don't want women to suffer through their pregnancy if they don't have to." To that end, Getty has created a PAM website, which she conceived of as "a place where women can feel supported, and find information they can trust."

While Getty personally tends toward a holistic lifestyle, PAM won't just promote one yoga-mama ideal. Instead, the site will provide a breadth of health information, including advice from pediatrician Alan Greene, author of Raising Baby Green (Jossey-Bass). It will also include a forum where moms-to-be can swap tips on everything from exercise to breastfeeding. "So many women struggle to get their babies to latch on," says Getty. "I did, and it was so frustrating that I almost gave up."

It's hard to imagine her throwing in the burping towel. After all, this is a woman who had a seriously no-nonsense preconception plan. "I took a year to plan my wedding," says Getty, who married screenwriter Gregory Pruss in 2003. "So I figured I should take a year to prepare for getting pregnant." Her regimen included regular meditation, abstaining from sugar, and earning certification to teach prenatal yoga. Though Getty conceived unexpectedly just six months into the plan, she remained enviably disciplined about sticking to it—mostly. "I did have some sugar," she admits. "One morning, I drove to a store just for coffee ice cream."

These days, between organizing PAM and developing recipes for an upcoming cookbook (she's had culinary training as well), Getty is lucky if she can sneak in a sun salutation at day's end. "The struggle for all moms is finding the right balance," she says. She makes family dinners a priority—though even that can get a little tricky, given that Getty is a self-described "flexitarian" (she eats some meat and fish), while India is a vegetarian by choice: "My daughter recently asked me, 'You're eating fish, like Nemo?' And I said, 'Sometimes people make different choices, and that's okay.' I try not to be too dogmatic about anything."

I can't believe I forgot to...
"...buckle India into her car seat one time. I had driven three blocks from my house when she told me. I just about died."

The unhealthiest thing I ever passed off as dinner is...
"...Pizza Pockets."

My favorite moment of the day is...
"...when my daughter walks in the door from preschool and says, 'Mama.'"

My mom was wrong about...
"...cooking being a thankless job. I love cooking for my family and friends."

As a parent, I'm great at...
"...communicating with my daughter."

As a parent, I wish I were better at...
"...communicating with my daughter."
