Their rules apply to others
If you thought the Duggar’s rules couldn’t get weirder, you’re in for a treat. One time, when Jill was training to become a midwife, one of her unmarried, pregnant friends asked her for help. Initially, mom and dad had no problem with their daughter lending out a helping hand (who wouldn’t?), but after learning that the friend wasn’t married, they changed their minds completely.
Imagine having that awkward conversation with your friend. “Sorry, I can’t help you with your pregnancy, despite me being a midwife, because… well… mom said no.” Why was it mom’s business in the first place? Nobody will ever know.
