The document examines Canada's policy recommending that women abstain from alcohol during pregnancy to prevent fetal alcohol spectrum disorder (FASD). While the policy's message has been widely received, some research shows light drinking does not increase social/emotional or cognitive risks for children. The unequivocal "no drinking" message promotes a certain viewpoint of appropriate maternal behavior without acknowledging scientific uncertainties. By shaping perceptions of risk and the psyche of modern motherhood, the policy functions as an effective mechanism of social control through moral straightjacketing of maternal conduct.
