Subacute Gummy Vitamin Overdose as a Rare Manifestation of Child Neglect.

We present a case of a 20-month-old girl who presented to the emergency department with anorexia, progressive weakness, and lethargy who was found to have severe hypercalcemia (20.7 mg/dL) and vitamin D hypervitaminosis. Further questioning revealed that this was secondary to a subacute toxic ingestion of "L'il Critters" calcium and vitamin D3 gummy vitamins that were being administered by the patient's mother multiple times a day for several weeks or even months.
