By what age do children typically show concern for a crying friend and…

Concept

Developmental milestones describe abilities that most children can demonstrate by a given age; they are age-linked guides rather than exact deadlines. Social-emotional milestones include empathy toward peers and an emerging understanding of possession and relationships.

Application

Standard three-year social-emotional milestone lists include showing concern for a crying friend and understanding ideas such as "mine" and "his" or "hers." These two cues therefore point to the three-year milestone.

Cross-check and contrast

• Twelve months marks the end of the first year, when social responses are emerging but the paired peer-empathy and possessive-concept milestone is placed later.

• Six months is mid-infancy, when emotional responses are present but the paired milestone in the stem is not yet the standard age expectation.

• Five years is later than the standard milestone age; children at that stage usually show more advanced cooperation and rule awareness.

Therefore, the best-supported offered answer is 3 years old.
