Catelynn Baltierra (née Lowell) was a junior in high school, living in Algonac, Michigan, when she and her boyfriend of three years, Tyler Baltierra, discovered that they were expecting a child together.

The show documents the couple, throughout the adoption process and shows prospective teen moms that there are options.
In May 2009, Lowell gave birth to a baby girl, who is named Carolyn Elizabeth (Carly for short) by her adoptive parents. Carly's adoptive parents are Brandon and Theresa. Lowell and Baltierra have an 'open' adoption with Carly’s adoptive parents, which means they receive photo's regularly and get to see their daughter in person once a year.
Lowell and Baltierra are step-siblings, as Lowell's mother married Baltierra's father. Their parents' relationship was extremely turbulent throughout the show. Lowell stated in 2012, that she'd be willing to go for custody of her younger brother if her mother "Fell off the wagon again". In 2013 it was reported that Lowell and Baltierra gained legal guardianship of a younger sister, this was later confirmed via Baltierra's twitter account .
