"Did you ever go to bed and wonder if your child was getting enough to eat?" For food insecure mothers, the worry is constant, and babies are at risk of going hungry. Out of Milk calls out the pressing need to establish the economic and social conditions necessary for successful breastfeeding and for accessible, reliable, and safe formula feeding for families everywhere. Through compelling interviews, Lesley Frank answers the breastfeeding paradox: why women who can least afford to buy infant formula are less likely to breastfeed. She reveals that what and how infants are fed is linked to the social and economic status of those who feed them. Out of Milk uncovers the shocking reality of food insecurity for formula-fed babies, the economic and social constraints limiting mothers' ability to breastfeed, and the lengths to which mothers must go to provide for their children. But in a country that leaves the problem of food insecurity to ineffective charity models, public policies are failing to support our most vulnerable populations.
