Quizplus · Accepted Answer

The Answer is 1) In the first year, social interaction between infants is not frequent, and when it does occur it is not sustained for very long
2) Between 12 and 18 months of age, infants become aware of their feelings and begin to realize that others have feelings as well, leading to increases in empathy and prosocial behavior
3) By 2 years of age, infants observe their peers' negative emotions carefully and attempt to respond appropriately
