Emily recently graduated college with a bachelor's in mathematics. She hoped to land a job in actuarial science, but her life plan has hit a few snags. First, she fell in love and got married. Then, she got pregnant. Now as a 23-year-old with a 4-month-old baby, she has a new career goal, at least for the short term: wet nursing.

While breast-feeding her own child, Emily became convinced of the matchless value of a mother's milk. "There might be some people out there who feel the same way, and who can't produce enough breast milk," she thought. "This might be a need I don't realize is out there."
