Many appeared on 16 & Pregnant and told their stories of having a baby while in high school, and when MTV created the Teen Mom spin-off, along with Teen Mom OG, fans got an inside look at the lives of Catelynn Lowell, Maci Bookout, Farrah Abraham, and Amber Portwood. Other cast members have joined since then, such as Bristol Palin, Cheyenne Floyd, and Mackenzie McKee, although not everyone has stayed on the show.

In the first season of the show, Catelynn went to a retreat one weekend, and this helped her connect with others who were going through a similar situation. She and Tyler decided that adoption was officially the right choice for them and they found Brandon and Teresa, the couple who adopted Carly.

There are many reality shows with unique settings and ideas, and while Teen Mom is filmed in a fairly straightforward way, as each episode moves between the main cast members, fans get an intimate look at what's going on in each person's life. Catelynn has always been very open and fans support her.

Catelynn And Tyler Visited With Carly After A Year Apart

In the season 2 finale, Catelynn and Tyler hadn't visited with Carly in a year, and they were able to see her again.

This was one of the show's most dramatic storylines and also a very emotional and heartwarming one. Catelynn and Tyler wore their hearts on their sleeve whenever they talked about Carly, as knowing that she was being raised by a loving family was so meaningful for them.

Sophia said that Farrah had "a bad attitude," and it was definitely surprising to hear a child say that to their parent. This was one of Farrah and Debra's most intense storylines on the show, and before this point, viewers had seen them experiencing tension for years.

Tyler Dealt With His Father Butch Coming Home From Jail

One reason why Tyler and Catelynn bonded so much when they first began dating was the fact that they didn't grow up in solid and happy homes. Fans who saw their episode of 16 & Pregnant and the early seasons of Teen Mom know that they had a really tough time when they were young.

In season 6, Tyler's father Butch was leaving jail, and Tyler had to deal with it. It's hard to imagine a more dramatic storyline than a child coping with their parent getting out of jail and adjusting to the world again.

Maci And Ryan's Co-Parenting Conflict

Maci and Tyler got married in season 6 and since then, fans have seen them struggle to co-parent with Maci's ex Ryan. Things have only gotten worse as time has gone on.

Maci and Ryan's tension over co-parenting has been one of the show's longest-running storylines and it's clear that it has been very difficult for Maci. While she always had a good relationship with Ryan's parents, who looked after Bentley often, things began to fall apart once Ryan began dating his now-wife Mackenzie. Other drama included whether Bentley would go to a birthday party being held for his brother as his dad was going, too, and it was at Bentley's grandparent's place.

Amber's Uncertain Engagement To Matt

In season 6, Amber was engaged to Matt, and this situation became very uncertain as she and viewers learned more about him.
