Nanny Accused of Baby's Antihistamine Overdose

An experienced nanny with over 20 years in the field, Sandra Davidson, is central to an investigation following the death of an eight-week-old baby. The infant was found unresponsive in January 2024, with a later toxicology report revealing a sedative antihistamine in his system. The Inner West London coroner's court concluded it was probable that Davidson administered chlorphenamine to sedate the baby, who had been described as unsettled.

Police were criticized for missing crucial forensic opportunities during their initial examination of the baby's home. A half-empty bottle of liquid antihistamine was found at Davidson's residence during a later search, by which time significant evidence may have been lost. The cause of death was officially listed as sudden unexpected death in infancy, though the drug's potential contribution could not be definitively proven.

The case has highlighted severe shortcomings in the regulation of childcare professionals. Unlike other sectors, nannying remains largely unsupervised, prompting widespread calls for mandatory background checks, standardized training, and the establishment of a national registry to ensure nannies are qualified and properly vetted.
