Look, if you're raised with 18 siblings, there's a good chance that you're not going to be friends which each and every one of them…and that's of course not a theoretical because we're flatly talking about the Duggars. Like, come on, what other family has 19 kids (OK, besides the Bates)? But seriously, we're realistic about the fact that even though the family claims to be so close, some sibs are closer than others. Usually being close in age helps, but sometimes bonding over small things brings two Duggars together. Like, Jessa and Jinger seem to be tight because they're not only 400-ish days apart, but they have a superficial love of "fashion." "Jessa's really into fashion, she's the one who got us all into it," Jinger shared in one video. To which Jessa faux-giggles, "No, that's you!" Actually, tbh, it seems that everyone has pretty strong feelings about Jessa, whether positive or passive-agressively negative.

But we'll get into that. Out of morbid curiosity, we decided to take a deeper look at the relationships between each sibling (i.e. paged through Instagram and old episodes for hints) to determine which siblings are friends or, beneath the surface, foes. So which Duggar siblings are closest? Click through our gallery to learn more about the interpersonal relationships between the Duggar kids.
