This case illustrates the medical complication of a child that arose as a consequence of parents with intellectual disabilities in a primary care setting. A 9-month-old girl presented with multiple admissions because of recurrent pneumonia and was later diagnosed with failure to thrive based on child neglect resulting from the parents’ disabilities. This exemplifies a failure to thrive case with a complex and undiagnosed psychosocial background that required interdepartmental involvement to mitigate the health problem.
