Jill Duggar Dillard is no stranger to sharing the reality of her fundamentalist upbringing. In 2015, reports surfaced alleging that Josh, the eldest Duggar son, had molested several girls as a teenager. Months later, Jill and her sister, Jessa Duggar Seewald, revealed in a "Kelly File" interview that their brother had abused them too (via Us Weekly). Jill ultimately forgave him. Maybe witnessing challenges to her parents' belief system helped her develop a good strength of character. 

She indicated in the first episode of the docuseries that her grandparents made their disapproval of her parents' lifestyle known. In particular, her grandparents disliked how the IBLP doctrine directly affected their family life. Jill shared, "My parents believed you should have as many kids as you're capable of having until your body tells you to stop. My grandparents, neither one on either side agreed with my parents having a million kids." 

Jill continued, "They were, like, concerned about my mom's health, and like they would always say 'Oh is this your last one?'" The docuseries could help provide some insight into the limits of organized religious groups for the Duggars and families like them. Executive producer Julia Willoughby Nason told People that she and her team "Hope our series encourages people to find their voice and to speak out and be brave and take the risk and have a new type of faith."
