Because of the rise in teenage pregnancies, many child development teachers believe that it is important to focus a large section of their instruction on how much responsibility having a child really is. To do this, they might give each student an egg to carry around for several days or a week as their “baby.” Students may not leave the egg alone and must take care to make sure that it does not break. Students are required to journal about the "baby's" welfare.
In recent years, this tried-and-true child development class activity has been replaced by dolls that are programmed to act somewhat like a regular baby. The dolls need to be fed, changed, or held when they cry. (Some less technologically advanced dolls just need one reaction when they cry, such as turning a key in the doll’s back.) After each student has a turn with the doll, the teacher can print out a report that shows how responsive each student was to the doll’s “needs.”
