Monstrous Mothering: Understanding the Causes of and Responses to Infanticide

The deliberate killing of a child by its mother is abhorrent and is associated in the minds of many with mental illness and in particular with postnatal depression. However, at least 50% of perpetrators are neither "mad" nor "bad", and mothers who kill children are not "unhinged" by pregnancy or childbirth. We propose a different explanation: "blind rage" or "overwhelmed syndrome", whereby parents, stressed to breaking point by sleep deprivation or incessant baby crying, respond by lethally harming their child contrary to previous behaviour. The roots of this blind rage may be found in psychosocial disturbances, including the mother's own unsatisfactory experience of parenting which has caused attachment disorders. The legal framework guiding decisions to prosecute and structuring sentencing decision-making following conviction should acknowledge the exceptional stress experienced by such mothers postnatally. Health professionals including midwives and obstetricians should increase their vigilance and arrange referrals for mothers at risk of causing harm or committing infanticide.
