A six-episode commitment is in place for The Baby Borrowers, a new reality series for NBC in which teenage couples are taken through the gauntlet of parenthood in just one month, during which they must care for a baby, then a toddler, then a pre-teen, and finally, grandparents. The new series is based on the popular British series of the same name, and the five couples featured on the show will be supervised at all times. Otherwise, the show would be called something like, Abandoned Babies, which doesn't exactly sell commercial time.
