Paternal postnatal depression (PND) is a condition that negatively affects fathers to a largely similar extent as mothers. Despite this, it is not commonly understood in society, which translates into a lack of support for fathers in healthcare settings. Fathers' PND experiences are different from those of mothers with PND, including anger, denial, and increased suicide risk. The impact of paternal PND is not only limited to fathers, with the condition being linked to depression in mothers, and issues around the psychological wellbeing of children. Nurses may face barriers in their knowledge of paternal PND due to a lack of historic research, but can use their own professional skills, incorporating NMC values, alongside the lived experiences of fathers, to provide support and care to depressed fathers. Using a family-centred approach is of benefit when supporting fathers with PND, and can reduce stigma and support fathers disclosing depression and help-seeking.
