In the premiere, we meet the teenage couples as they reach the final stages of a pregnancy as each girl wears a fake belly. Then, the big day arrives as the newborns are placed with their couples.
A pair of the moms decide to search for jobs. Later, the infants are returned to their parents by the teens and the teens receive their first review.
The next challenge for the teens is to take care of toddlers, which includes potty training and throwing a birthday party. One of the guys is left to care for twins, while his partner heads off to work, and another teen calls it quits after receiving criticism from the child's parents.
The teen "parents" are challenged to care for preteens, including one couple who organize a slumber party for all nine of the kids, and any plans for a quiet evening for the remaining teens may end when an unexpected surprise arises.
The teen couples will next be challenged to watch over and manage the problems of other teens. This seems too much for one of the couples, who's relationship was already on shaky ground.
The first season comes to a close as the couples are left to care for the elderly. Also, the teens give an update on their lives since the series began.
The producers and cast reunite for a town hall style reunion as they recount their experiences while on the series.
