Final answer:
Self-awareness in children develops gradually in different stages of early childhood, starting with self-recognition in mirrors around 18 months and progressing to a self-concept by 4 years old.
Step-by-step explanation:
The development of self-awareness in children occurs gradually in different stages of their early childhood. Around 18 months, toddlers start recognizing themselves in the mirror, indicating self-recognition.
Between 2-4 years old, children develop a self-concept and show an increase in social behavior. They can name themselves in pictures and explore their gender roles.
By 6 years old, children can identify themselves in terms of group memberships and recognize their own personality traits as well as desires to possess certain traits of others.
