Breastfeeding in the 21st century: How we can make it work

There is abundant knowledge on the major health and social benefits of breastfeeding, and on how to protect, promote, and support breastfeeding. Hence, it is surprising that recommended breastfeeding behaviors continue to be suboptimal in the 21st Century among large segments of the population, globally. Moving forward, it is crucial to enable the breastfeeding environments for women through family friendly employment policies and to enforce the WHO Code for Marketing of Breastmilk Substitutes. It is also key to invest more in training the workforce for successful large-scale implementation and sustainability of the Baby Friendly Hospital Initiative, community-based breastfeeding counseling, and to prevent conflicts of interests with infant formula companies. Behavior change social marketing interventions that include social media need to be designed following social network science and behavioral economics principles. Evidence-informed policy tools are now available to help policy makers invest in and guide the scaling-up of cost-effective breastfeeding programs.
