Growing Up (E02)

Any parent knows about the problems of bringing up a child, and for animals it is no different. How do you protect your infant from daily hazards, care for it in a busy schedule, and help it survive the vulnerable years to achieve independence? How does an infant learn the skills it will need for life? From creches of bats to elephant babysitters, from chimpanzee games to protective lacebugs, nature's answers are as varied as those in human societies. (BBC)
