When you become a mom, you become sensitive to the whole world. You want to feed the hungry, cure the sick and make the world a better place. Some moms take that feeling so far that they transform a cause into a business. We all want to make the world a better place. These moms are actually doing it. They are moms on a mission.

Diep Nguyen, M.D., kickTrak
Dr. Diep Nguyen developed kickTrak, a product that is dedicated to preventing stillbirths through kick counting, a safe and simple pregnancy health practice. KickTrak is a handheld, noninvasive device to make it easier for moms-to-be to track their baby's movements. Nguyen also developed the nonprofit BabyKick Foundation, which provides research and works with international organizations to educate parents, health care providers and policy makers about the importance of being aware of decreased fetal movement to reduce the risk of stillbirths.

Nguyen designed kickTrak in response to her patients, who wanted to keep reliable records of their kick-counting sessions rather than rely on their memory. KickTrak allows moms to press a button each time they feel their baby move during once-daily kick-count sessions, and it keeps a digital record that moms can share with their doctors.

Nguyen's commitment is not only professional; it's very close to her heart. Her mother lost a baby to stillbirth and another sister avoided a similar tragedy by noticing decreased fetal movement through kick counting. Nguyen's efforts are gaining national attention, as she been invited to speak on Capitol Hill about kick counting several times.

Alyssa Dver, Wander Wear Inc.
Alyssa Dver is the founder of Wander Wear and The Center to Prevent Lost Children. 

Did you know that seven out of 10 children get lost at least once in their lifetime? When a child wanders, it can cause lifelong trauma for both caregiver and child. Yet fewer than 9 percent of parents are prepared. Dver, an accomplished software marketing executive, author and mom, one day discovered a new purpose in life by helping to prevent children from getting lost.

She started by launching Wander Wear Inc. with a cute company mascot, Whizzly. She offers products that include parent locator tags, easy-to-spot children's clothes and a book, When Whizzly Wanders, that teaches kids what to do if they get lost.

Joanne Goldblum, The Diaper Bank
Social worker Joanne Goldblum was unable to wrap her head around the uncomfortable truth that a significant population of American children grow up in conditions so poor that clean diapers aren't a given. Frustrated but inspired, she saw a need she could address: distributing diapers to the poor. Goldblum created The Diaper Bank, a nonprofit organization that distributes diapers to the poor. Goldblum held the first diaper distribution in her home in July 2004, providing almost 5,000 diapers. During the past five years, The Diaper Bank has distributed more than 5 million free diapers to families.

Goldblum has been recognized not only in local media but also nationally in People magazine and on CNN, and she was named the New Haven Register Person of the Year 2007. She has helped thousands of children over the years, and her company is nearly 100 percent volunteer-driven.

We become mom entrepreneurs for many reasons. Most often, it's because we want a career that's supportive of motherhood. I'm so proud of all the moms who also create businesses that make our world a better place.
