IntroductionSocial support has been identified in the literature as a key facilitator of breastfeeding success among Black mothers. Over the past decade, there has been a surge of social media groups that can now be used as a means of support for various health and social issues. Social media breastfeeding groups have been used as sources of additional support. A scoping review of the literature was conducted to explore social media usage as a form of social support among Black women in the postpartum period and how it may affect breastfeeding behaviors.MethodsUsing the 5‐stage scoping review methodology, scholarly databases were searched for relevant articles. English‐language articles on studies conducted both in and outside of the United States were included. Original studies that focused on social media as a form of breastfeeding support and included Black mothers as part of the study population were included.ResultsAfter screening 551 articles, 6 studies fulfilled the study criteria. Participants reported being provided with various forms of social support through social media within the included articles. Primary themes included (1) a sense of community and (2) self‐efficacy and empowerment. Breastfeeding support through social media appears to positively influence breastfeeding intention and duration rates among Black mothers.DiscussionSocial media is an accessible avenue for breastfeeding information and support. Moreover, it provides a safe space for Black women to interact with others of shared cultural experiences. Therefore, incorporating social media into breastfeeding interventions can positively affect breastfeeding rates among Black women. More research is needed to assess the direct effect of social media breastfeeding support groups on the breastfeeding behaviors and experiences of Black women.
