A very motivated high school senior, Kailyn is the serious and stoic teen mom of baby Isaac from Nazareth, Pennsylvania. After discovering that she was pregnant with her boyfriend Jo's baby, Kailyn tried hiding the pregnancy for as long as possible from her classmates and friends. However, once she had to quit the Lacrosse team, everyone discovered her secret. With ongoing battles with her mother leaving her with no place to go, Kailyn was taken in by Jo's family who supported her throughout her pregnancy.
Kailyn and Jo's relationship begins to crumble under the stress of balancing their lives and raising Isaac. The non-stop fighting is wearing thin on Jo's family, and the two break up, with Kailyn continuing to live at the house, but this time in the basement. When she starts dating someone new, Jo and his family find out and she is forced to move back in with her unsupportive mother. To insure that she can independently support herself and Isaac, Kailyn juggles two part time jobs and a full course load at the community college while dating and being a full time mommy.
She hopes that all of her hard work will one day pay off with a successful career as a dental hygienist and a stable home for her favorite boy, Isaac.
