Dr. Erikson, who died in 1994, theorized that personality is developed through eight different life stages, later called Erik Erikson’s stages of psychosocial development.

Meanwhile, they continue to progress through subsequent stages.‌ Stage 1 — Infancy. During this stage, development centers around trust and mistrust.

Autonomy versus shame and doubt is the second stage of Erik Erikson ’s stages of psychosocial development. This stage occurs between the age of 18 months and around age 2 or 3 years.

In Stage 2, the toddler is developing their will rather than only following others’ dictates. In Stage 3, the child is developing purpose. In Stage 4, the child develops competence.
