Bill Klein, a businessman, and his wife, Dr. Jen Arnold, both suffer from skeletal dysplasia, a type of dwarfism. The show’s initial focus was on living with dwarfism, but as the series progressed, it became more about raising a family and finding a dream home, making the family more relatable.
Due to their physical condition, the pair has endured a lot of difficulties and challenges, but they’ve always been there for each other.
Klein and Arnold, on the other hand, have known each other since before the TLC show premiered in 2009. They first met as children!
