To assess the age of the initial prosocial manifestations and repertoire of young children, 129 orphans' prosocial episodes from their anecdotal records were analysed. These 562 episodes were directed towards nurses (72 cases), peers (470 cases), animals (9 cases), and dolls (11 cases). Little orphans in the second and third years of life showed many forms of prosocial behaviors; "helping", "giving", "nurturing", and "comforting". The results of 613 children who entered the orphanage under 1-year of age indicated that a 9-month-old girl initially displayed a prosocial behavior by comforting a crying baby, half of the children displayed prosocial behaviors within 113-months of age and most within 30-months of ale. In the cases of prosocial episodes towards other children, 2-year-olds behaved prosocially to the younger more often than to the older, and 2 1/2 to 3-year-olds did so with an air of an older brother/sister to toddlers at least one year younger than themselves.
