Borderline personality disorder (BPD) is highly prevalent in clinical perinatal mental health settings, although there are few systematic programmes to identify BPD at this time. Retrospective studies show compromised birth outcomes for women with this condition, and several authors have highlighted a significant range of problem outcomes for offspring identifiable from early infancy through the adult years, including the intergenerational transfer of mental health problems from mother to child. A literature review identifies the varying prevalence rates found in non-clinical and clinical settings and the paucity of published studies on the management of perinatal BPD, in particular focused both on the mother and mother-infant relationships. A case study is presented to show both the potential benefits of inpatient mother-baby unit protocols and of specialised longer-term group therapy. Many knowledge gaps can be identified for further clinical research that could potentially benefit families with perinatal BPD, including systematic identification of perinatal BPD and intensive programmes that not only could perhaps improve birth outcomes but also provide skills to mothers to help with their emotional regulation and potentially improve mother-infant relationships and longer-term offspring developmental pathways.
