Obstetricians and other obstetric providers play a critical role in promoting, protecting, and supporting breastfeeding. Most obstetricians agree that they have a role in breastfeeding support and promotion; however, they often feel unprepared to do so. Breastfeeding support from clinicians is a highly modifiable barrier to breastfeeding success and physician education in breastfeeding medicine is vital to the provision of optimal obstetric care. Obstetricians can easily utilize numerous existing online and print resources to improve their own knowledge, making them an invaluable resource to their patients.
