Will NBC renew 'Baby Borrowers'?

Not in the same format.

NBC's child-rearing reality series cracked the top 10 shows of the summer and was the third-highest-rated new show (behind ABC's renewed "Wipeout" and doomed "I Survived a Japanese Game Show"). But "Baby Borrowers" dropped from its 2.9 premiere rating to a 2.1 for its finale.

The problem, some believe, was the teen parents were given dependents of varying age throughout the series. Once their babies "grew up," viewer interest waned. By the time the teens were changing diapers on senior citizens instead of babies, it was as if the show's title was no longer accurate.

Plus, "Borrowers" seemed to catch the zeitgeist of the whole post-"Juno"/"Knocked Up"/"Secret Life of the American Teenager" baby-bump boom. Will viewers still respond to the concept next year?

NBC hasn't entirely given up. Executives are brainstorming possible format changes to make the show work for another round. The U.K. version of the show attempted a second season called "The Baby Borrowers on Holiday" to shake things up. But it didn't do so hot.
