The teen moms are back – and so are their problems.
In the second season of Teen Mom 2, cameras once again follow Kailyn Lowry, Jenelle Evans, Leah Simms and Chelsea Houska as they struggle to raise their children while facing everything from health scares to jail time, alcohol abuse, infidelity and divorce.
"As their babies are growing, so are their challenges," the trailer for the second season says.
Teen Mom 2 premieres Dec. 6 (10 p.m. ET) on MTV.
