Red flags

  • Early postpartum rapid insomnia, confusion, mania, or psychosis — treat as postpartum psychosis emergency with mother and infant safety plan
  • Ego-syntonic delusions or command hallucinations involving infant harm — psychosis pathway and safeguarding, not reassurance alone
  • Active maternal suicidal plan or intent on maternity/medical ward — intensify observation and joint obstetric-psychiatric care
  • Fluctuating confusion with hypertension, fever, or focal neurology — exclude eclampsia, infection, and organic causes before pure psychiatric labelling
  • Abrupt stop of lithium or effective mood stabiliser at conception without a written relapse-prevention plan
  • Valproate in pregnancy-capable patients without exceptional documented safeguards — major teratogen
  • Processing irreversible obstetric refusals or discharge with infant while capacity is impaired by psychosis, delirium, or severe depression

The one-line answer

Perinatal psychiatry in the general hospital is CL work across maternity and medical wards: separate blues, depression and anxiety, OCD, and postpartum psychosis; exclude medical mimics; protect mother and infant; use the EPDS as a screen, not a diagnosis; prescribe with pregnancy and lactation risk-benefit (sertraline often preferred postpartum); run lithium peri-delivery and ECT pathways when severity demands; and disposition via mother-baby unit or joint obstetric-psychiatric plans under local law.[5][7][8][12][16]

Meet the patient

Day 5 after an uneventful delivery, a 31-year-old first-time mother has not slept for three nights — and is not tired. She is perplexed, rapid in her speech, and convinced the baby in the cot is not hers. The midwife found her standing at the nursery window at 4am, praying aloud.[5][8]

The obstetric team have asked whether she can be discharged home tomorrow with "some sleeping tablets." Two questions must be answered first, and they are not about sedation. Is this postpartum psychosis? And is the infant safe with her tonight? Everything below exists to answer both at consultant depth.[5][12]
