How freud theories can apply to a 3 year old child?

Freud's theories, such as the Oedipus complex and development of the ego, can be applied to a 3-year-old child by understanding their early experiences and internal conflicts. For instance, the child may exhibit behaviors related to resolving the Oedipus complex by identifying with the same-sex parent. Understanding these dynamics can provide insights into the child's emotional and social development.
