4x17 - Step by Step

Everyone begins to help Carol so she will not be stressed out too much and harm the baby. Carol, however, is so fussy about how they help that she drives them all crazy and seems to be just as stressed. Brendan, however, stays up all night cleaning to help. Dana and Cody are selected to teach a bunch of remedial high school students about the Civil War. Cody signs them up for a hit TV game show, ""It's Academic,"" and wants a more hands-on kind of teaching. Dana fights Cody on both until the competition, where she gets so into it, she threatens her team. The students respond to both Cody's teaching and Dana's coaching.
