He developed the Psychosexual theory of development which proposes that the psychological development of a child occurs during each psychosexual stages which include; Oral, AnaI, Phallic, Latency and Genital, and that these stages are related each to a different physical center of pleasure.
During this stage, the child derives pleasure in defecating as the pleasure is now focused on the anus. The child's ego is now developed and they are now aware of their own rights. They can also be stubborn and tight-fisted and controlling with their possessions. As the child grows they might get stuck at this stage of development if not looked into.
