During early childhood, children make enormous gains in the development of their concepts of self and the ways they interact with family and friends.
From age 1 year to 4 years, children begin to develop a sense of themselves as separate from their parents and caregivers. They have increased self-control and respond appropriately to life experiences by delaying gratification, modulating responses, remaining calm, focusing on tasks, recognizing consequences, and complying with rules. Parents continue to be the major influences and facilitators of healthy development during early childhood.
