Before their third birthday, most children are easily able to label themselves as either a boy or a girl. By age four, most children have a stable sense of their gender identity.

Before the age of three, children can difÂ­ferentiate toys typically used by boys or girls and begin to play with children of their own gender in activities identified with that gender.
