• Correction notice This paper has been amended since it was published Online First. In paragraph 10, the second sentence has been changed with the addition of the underlined words: “Few bruises are pathognomonic of non-accidental injury. In this study, two bruises to the cheek were noted from multiple data collections from premobile infants and two bruises to the ear in collections from early mobile infants—both rare sites for accidental injuries in any age group in my experience.” In addition to these changes, the final paragraph has been revised.
