An exclusive sneak peek into the season 10 premiere of Teen Mom 2.

For four seasons fans of "Teen Mom" watched Maci, Amber and Catelynn face multiple challenges in their first years of motherhood, including such things as graduating from high school, relationships, getting jobs, beginning college and moving out on their own. Oh, and raising their first child. Now the original girls -- hence, the "OG" in the revived series title -- return to reveal the challenges of raising children on camera, and how life in the public eye has shaped them as parents and people. It's an unprecedented view of young mothers facing the responsibilities of parenthood as their children enter kindergarten, start little league and reach other milestones of youth.

"Teen Mom" debuted on MTV in 2009 and soon after garnered accolades for bringing attention to the issue of teenage pregnancies. The series even was cited for helping to lower teen birth rates by 46 percent since it premiered. MTV continues the "Teen Mom" legacy with "Young and Pregnant," which chronicles diverse stories and backgrounds of young women and the challenges they face in their first years of being a Gen Z mother.

"High School Moms" goes into the halls of an exclusive Denver high school. It's filled with girls, and the only time a boy is allowed in is when his mother is enrolled. You see, at Florence Crittenton High School, every student is either a teenage mother or a pregnant girl. The series provides a glimpse into the lives of teens who not only are working toward getting their high-school diplomas but also are tackling the responsibilities of caring for a baby or preparing for motherhood. The school offers plenty of opportunities to succeed by providing nursing facilities and an on-site day care center, but daily challenges force some of the teens to question if graduating is even worth it.
