Despite the central place of suffering in medical care, suffering in infants and nonverbal children remains poorly defined. There are epistemic problems in the detection and treatment of suffering in infants and normative problems in determining what is in their best interests. A lack of agreement on definitions of infant suffering leads to misunderstanding, mistrust, and even conflict amongst clinicians and parents. It also allows biases around intensive care and disability to affect medical decision-making on behalf of infants. In this (...) paper, I propose the concept of suffering pluralism, which is a novel multidimensional view of infant suffering based on subjective and objective components. The concept of suffering pluralism is more inclusive of the multiple ways in which infant suffering can occur. It acknowledges and defines a subjective component to infant suffering, while also focusing moral attention on objective well-being by describing it using the language of suffering. This concept allows us to better weigh up subjective and objective components of well-being. It also encourages clarity and consistency in claiming suffering, which is likely to improve communication and reduce conflict in medical decision-making for unwell infants and children. I will end by exploring possible critiques and limitations of this concept. (shrink)
