Jenelle, Chelsea, Kailyn, and Leah are four young women navigating complicated lives. It's not always easy being a young mom.

This hourlong documentary series focuses on the issue of teen pregnancy, with each episode detailing the wide variety of challenges -- marriage, adoption, finances, gossip and graduating high school among them — a pregnant teenager faces while still coming of age.

The casts of Teen Mom OG and Teen Mom 2 are each currently in different stages of motherhood - some have kids in diapers, while others are now parenting teenagers! But they all share the unique experience of momming so young. For the first time, the moms and all their stories will be brought together in one supersized series that focuses on the unique bond this "Mom Group" shares as they face the reality of parenthood and adulting while entering this next phase of life together.

What mom doesn't need a break? That's why cast members from across the Teen Mom franchise are coming together for a tropical vacation. But it's not all rest and relaxation, as the moms dive deep into relationship, friendship and parenting issues.
