Feel-Good Follow-Up

Ok here's some hope in the face of the last bullying post: A very heartwarming story about how babies in the classroom can increase kids' empathy and decrease aggression.

The comments are good, too; several people make the very valid point that today's smaller families, greater distance from extended family members, and various social structures and institutions that segregate people by age probably don't do us any favors in terms of teaching empathy or nuanced social skills.

Anyone witnessed positive changes in older children's behavior when a sibling comes along? Experienced a great mixed-age school or playgroup? Sought out time at a nursing home or other place where kids could encounter older folks?
