When Maci Bookout, Catelynn Lowell, Amber Portwood and Farrah Abraham make their highly anticipated return to MTV, viewers will witness a new way of telling the young mothers' stories.

"Teen Mom OG," featuring the original four cast members, will bow on the network Monday, March 23; while cameras and production teams haven't been visible on-screen during previous seasons, the upcoming installment will feature a close look at the actual filming (e.g. action slates and cast members putting on their microphones) -- plus the ladies' personal connections with behind-the-scenes folks.

"'Teen Mom OG' will break the fourth wall, pulling back the curtain to reveal their relationships with the producers and crew, the challenges of raising children on camera, and how life in the public eye has shaped them as parents and people," MTV explained in a press release. Fans of the show will continue to watch M, C, A and F as they rear their children -- from helping them reach developmental milestones to beginning kindergarten and competing in their first sporting events. The mothers will also face new challenges of their own, as evidenced in the four sneak peeks of "TMOG" below.

With our first glimpse of Maci (who has found love with longtime boyfriend Taylor and is gearing up for kiddo No.2's debut), we see the redhead continue to have struggles co-parenting with her ex Ryan. In fact, Bentley's dad is late during a dropoff/pickup in the video below, so will the former couple be able to get past their long-looming communication issues?

Meanwhile, Catelynn and Tyler are getting ready to welcome a baby and have invited their nearest and dearest to find out their bundle of joy's gender. Who's hoping for a boy, and who's pulling for a girl? The video below tells all!

Amber, who has just been released from prison, is still trying to get along with her ex Gary -- who happens to be expecting another child with his girlfriend Kristina. But in the clip below, Leah's parents continue to wrangle with their own issues with one another -- and their candid conversation quickly gets heated.

And last, but certainly not least, Farrah is balancing motherhood, trying to mend relations with her mother and juggling a long-distance relationship -- her first such connection since the death of Sophia's dad. So how does Farrah make her slightly belated entrance on the show? The moment below shows it unfold -- in dramatic fashion.
