BackgroundBreastfeeding has numerous health benefits. In 2010, the province of Newfoundland and Labrador had the lowest breastfeeding initiation rate (64.0%) in Canada. Formula feeding is associated with well-known health risks. Exclusive formula feeding is the “cultural norm” in some regions of the province. Women appear resistant to changing their infant feeding behaviors and remain committed to their decision to formula-feed. The primary aim of this qualitative study was to examine individual factors that shaped mothers’ decisions to formula-feed their infants. Nineteen mothers who were currently formula feeding their children participated in the study.MethodsQualitative research in the form of focus groups was conducted in three communities in the province in 2010. A thematic content analysis identified the main themes that influenced mothers’ decisions to formula-feed their infants.ResultsThe main themes included issues concerning the support needed to breastfeed, the convenience associated with formula feeding, and the embarrassment surrounding breastfeeding in public.ConclusionsThese findings help to better understand why mothers choose formula feeding over breastfeeding and may help to inform the development of public health interventions targeted at this population of mothers.
