Which stage in Freud's model is characterized by the focus on pleasure derived from the mouth?

The oral stage is the first phase in Freud's psychosexual development theory, occurring from birth to about 18 months. During this stage, an infant's primary source of interaction with the world is through the mouth, which provides pleasure and comfort. Activities such as sucking, biting, and chewing are central to the child’s developmental experience. According to Freud, how caregivers fulfill these oral needs can shape personality traits—those weaned too early may develop issues related to dependency or aggression, while those who experience a more nurturing approach may develop a sense of trust.

The other stages in Freud's model—anal, phallic, and genital—represent different focuses of pleasure and development that come later in a person's growth trajectory. In summary, the oral stage is distinctly recognized for its emphasis on oral gratification and its significant role in shaping early personality traits.
