Promoting cooperative social behavior is a major task of preschool teachers. Children are taught to be nice, be fair, and share. This mandate, however, runs up against the fact that young children are naturally egotistical and unable to appreciate the perspective of others. This leaves teachers with questions about how strongly they should push the be-nice agenda when it meets with resistance. Joan Goodman and Maya Rabinowitz explore how teachers of young children can reconcile their goals both to respect children's natural development and to socialize them.
