With the Duggar family, comes the Duggar rules. The famous family is notorious for keeping their children on a tight leash (so to speak), and only loosen the grip after their kids' exchange vows. But, as it turns out, Jinger isn't the only rebellious one of the bunch. Her brother, Josiah Duggar, showed his own defiance by having an Instagram account before proposing to fiancée Lauren Swanson — a strict no-no according to Jim Bob and Michelle.

So, now that Josiah and Lauren are engaged, fans are wondering why his courtship was the exception to the rule. Usually, Jim Bob and Michelle only approve of their children creating Facebook, Twitter, and Instagram accounts after their engagements are official. In fact, all of the Duggar kids except for Josiah followed their wishes.

Josiah announced his proposal on March 5 writing, "I feel like the most blessed guy on earth ?… Lauren said YES! God definitely opened our eyes in his perfect timing to show us how we complete each other. The more time I spend with Lauren the more I realize how I can't live without her. There's no one else I'd rather spend my days and grow old with!"

But, unlike his siblings, he was on IG and Twitter years he became a fiancé. He used social media during his previous ill-fated courtship with Marjorie Jackson in 2015, and it looks like he never left. So, maybe Josiah isn't afraid to do his own thing? When he and Lauren were still courting, he posted a photo of them Facetiming and there was no chaperone in sight. If they're this bold before they're married — we wonder what they'll be like after they say "I do."
