There are several reasons some mothers may not be able to breastfeed. Some are not able to produce enough milk. Others might be taking medicines or have medical problems that prevent the process.

　　Lucy Baur lives near Fort Wayne. She fed her milk to both her children and always had more milk than they needed. She wanted to donate to the Indiana Mothers Milk Bank in Indianapolis. But freezing and shipping milk can be costly. Then, a donor station opened near her home.

　　Milk donations in the United States work like this: Donors must be willing to provide almost three liters of breast milk. They freeze the milk and take it to the station. There, employees warm the milk and mix it with other mothers’ milk. Then, the milk is heated to kill bacteria. After that, the technicians test samples of all the milk to make sure it is safe and healthful. The milk is refrozen and sent to the main milk bank. The milk bank transports the milk to hospitals to feed premature or sick babies. Donors are tested for diseases before any milk is accepted. They are not permitted to smoke tobacco, use illegal drugs or drink too much alcohol. (370W)
