Final answer:
Melanie Klein would interpret a crying and kicking hungry infant as fantasizing about the breast disappearing, relating to her theory of object relations and the significance of the breast in an infant's life.
Step-by-step explanation:
If a hungry infant cries and kicks, Klein would say that it is fantasizing about the breast disappearing. Klein's theory revolves around the idea of the object relation which suggests that infants relate to aspects of the world in relation to parts of themselves. In this case, the infant's basic need is hunger, and the source to satisfy this hunger is often the breast through breastfeeding. So, in the context of psychoanalysis, Klein might interpret the infant's distress when hungry as a fear or fantasy of the breast, as the object meeting their needs, disappearing or being unavailable.
