With 19 children, it must be difficult for Jim Bob and Michelle Duggar to keep them all straight! While most American families average just two children per household, the famous family has more than nine times that amount. In other words, they need some serious organizational skills to make sure everyone is accounted for. Thankfully, we can always count on Jill Duggar to spill some juicy family secrets!

Late last week, the 27-year-old commented on a pic of the Bates' family brood and wrote, "This is so great!! We will have to do that at our next family photo session." She added, "Our lineup was called 'code O' lol."

Yet this isn't the only bit of info the former Counting On star recently dished. Back in 2014, Derick Dillard's wife revealed that her parents got a bit handsy before tying the knot, something they forbid their children from doing.

"So my parents, they um, did the traditional dating," Jill revealed in a resurfaced clip. "So when they were engaged, they spent a lot of time alone together. They said they saved intimacy for marriage, but they kissed." Gasp! Jill added, however, that they regretted their decision. Suuureee. "They wish they would've saved more of each other for themselves, and so, I think it's just neat to see the wisdom that they've spoken to our lives." She added that her parents said courting is a "neat idea."

ICYMI, the TLC fam abides by a strict form of dating known as courting — aka being romantically involved with the intention of marriage. Being in a courtship means mom and dad are cc'd on texts, full-frontal hugging is forbidden, and hand-holding is to be saved for an engagement.

Currently, only one Duggar is courtingJohn David and his girlfriend, Abbie Grace Burnett. Since the Duggars are known for their quickie engagements, though, we suspect another wedding will happen before the end of the year!
