Erin Curtiss is a midwife in Seattle. She is 34 years old, has sharp blue eyes and a raunchy sense of humor. She lives with her two young sons and her girlfriend. Erin, who runs her own home birth business, recently learned of an American nonprofit organization called Midwives for Haiti. She found it on Facebook. ... She traveled to a little city called Hinche, in Haiti’s Central Plateau. She came to volunteer at the public hospital, where patients are crammed into long rooms with no electricity, and where the windows and doors are open to the air – and the mosquitoes and flies and lizards that come through. Back home, Erin only deals with uncomplicated pregnancies, but here, women have extremely high blood pressure, anemia, even cholera. These are the sickest patients she has ever seen, and the hospital staff doesn’t seem to have enough time for anyone. Erin came here mostly to train midwives, but now that she sees how much needs to get done, she wants to do more. So she makes a generous offer. She’ll work the night shift, when there are fewer midwives on staff. ...
