Autonomy vs. shame and doubt is Erikson's term for the period during which toddlers (aged 18 months to 3 years) develop independence and autonomy if they are allowed the freedom to explore, or shame and self-doubt if they are restricted and overprotected. In this stage, they develop an important virtue of "will" where their parents play a major role in molding such quality. For example, they can learn at this stage on how to go to the toilet on their own or even clothe themselves.
