VIDEO: A Teen Mom's Twin Sister Struggles For Attention

Adding a newborn to a family can dramatically change the dynamic and energy of the household--we've seen that happen over and over again on Seasons 1 and 2 of "16 and Pregnant." When roles are forced to change, moods are tested and oftentimes we see people struggle to redefine their lives. The first episode of Season 3 (premieres April 19 at 10/9c) will explore these shifts even further.

Check out a sneak peek of the premiere, where new mom Jordan sees the way having a child has affected her twin sister, Jessica. Now that Jordan has a baby and live-in boyfriend, she doesn't have as much time for her sibling and it's causing a lot of tension in the house. Make sure to tune in on the 19th to see how it all unfolds.
