Maci, Farrah, Amber and Catelynn’s stories continue in their final season, and the challenges grow as the babies become toddlers, and really start to talk. Each episode interweaves all four stories as the young moms navigate the intense challenges of the first few years of motherhood. Faced with incredibly adult responsibilities, these young moms struggle to pursue their childhood dreams, and are often forced to sacrifice their teenage years, their high school experience, and their former ideas of what their lives would be. But there is optimism among them; they have the dedication to make their lives work. Though nearly children themselves, they have a drive to do as they see fit and try to provide the best for their children.
