A night nanny who was found to have caused the death of an eight-week-old baby by administering a sedative antihistamine has been identified as Sandra Davidson, a professional with over 20 years of experience. The infant was discovered unresponsive in his crib in the early hours of January 15, 2024, and despite resuscitation attempts, he was pronounced dead at 7am.
Initially, the Metropolitan Police found no obvious cause of death, but a toxicology report later revealed the presence of chlorphenamine, a sedative antihistamine, in the baby's bloodstream. The coroner's court concluded, on the balance of probabilities, that Davidson had administered the drug to sedate the baby, who was described as unsettled and frequently waking.
Investigation and Missed Opportunities
The inquest heard that a half-empty bottle of liquid Piriton was found at Davidson's home during a police search in October 2024, months after the baby's death. The prevention of future deaths report highlighted that police did not initially seize bottles or check for medications at the scene, missing crucial forensic opportunities. Detective Inspector in charge accepted that it would have been reasonable to check medicines in the home or in possession of those caring for the child, including the nanny.
Davidson was not arrested or interviewed until after forensic opportunities were lost, leading to the cause of death being listed as sudden unexpected death in infancy. The coroner noted that chlorphenamine, due to its sedative effects and association with child deaths, should not be given to such a young infant.
Regulatory Gaps Exposed
The case has reignited calls for mandatory background checks and a national register for nannies. Unlike other childcare sectors, the nanny industry remains largely unregulated. The Night Nannies agency, which connected Davidson to the family, stated that nannies are required to show references, an up-to-date DBS check, and first aid training, but are banned from administering medication. The agency has since stopped working with Davidson and expressed support for a national register.
The National Nanny Association has urged for standardised training, including first aid, child development, and safeguarding, as well as ongoing professional development. Alice Bell, co-founder of the association, stated: "While the majority of nannies are passionate and responsible carers, there will always be some that aren't. In an unregulated sector, children are dying."
Public Interest and Family Impact
The coroner allowed Davidson's name to be released due to significant public interest. The Metropolitan Police expressed condolences to the family and are formally responding to the coroner's concerns. The inquest found that the baby's home environment was in order, with no signs of injury or neglect, but the administration of chlorphenamine likely contributed to his death.
This tragedy has underscored the urgent need for oversight in the nanny industry to prevent future deaths and ensure the safety of children in professional care.
