Health professionals need support to breastfeed, like anyone else. The GP Infant Feeding Network lists resources for medical parents.
There is a Facebook group offering peer to peer support for breastfeeding doctors.
If you have had a difficult breastfeeding experience as a health professional it's important to come to terms with this in order to offer the families you work with unbiased advice - health professionals may have worse breastfeeding outcomes than expected, perhaps due to intensity of work demands, and this is correlated with strength of breastfeeding advocacy.
