Family Issues
Even though it may have been canceled multiple times, this show continues to come back thanks to the Roloff family. The family is made up of mother and father, Amy and Matthew Roloff, as well as their three children: Zach and Jeremy, the twins, and Molly. Interestingly, Zach is also a dwarf, while Jeremy and Molly are not.

The Roloffs are a unique family that wanted to show that no matter their size, they could overcome any obstacle. As a result, they are a unique family, with some small children and some of average height. This leads to all sorts of complex situations that the family must navigate.
