At around eight months of age, children show clear awareness of being a separate person and of being connected with other people. Children identify others as both distinct from and connected to themselves. (Fogel 2001, 347)
|
At around 18 months of age, children demonstrate awareness of their characteristics and express themselves as distinct persons with thoughts and feelings. Children also demonstrate expectations of others’ behaviors, responses, and characteristics on the basis of previous experiences with them. |
At around 36 months of age, children identify their feelings, needs, and interests, and identify themselves and others as members of one or more groups by referring to categories. (24–36 mos.; Fogel 2001, 415; 18–30 mos.)
|
For example, the child may:
-
Respond to someone who calls her name. (5–7 mos.; Parks 2004, 94; 9 mo.; Coplan 1993, 2)

-
Express thoughts and feelings by saying “no!” (18 mos.; Meisels and others 2003)
-
Move excitedly when approached by an infant care teacher who usually engages in active play.

-
Say own name. (30–33 mos.; Parks 2004, 115)
