Throughout her family's time in the spotlight, fans have been almost creepily fixated on the fact that Jana Duggar is still single.
Of course, you can't really blame Duggar obsessives for fixating on Jana's lack of a love life.
After all, this is a family that has taught their children from a young age that procreation is a woman's primary reason for being.
As a result, most of Jana's sisters married young and commenced with the business of making babies shortly after tying the knot.
Jana's decision not to follow suit has led her down a very different path than the one taken by the rest of her siblings.
Not only has she continued to live at home with her parents, in many ways Jana still plays the role she played as an adolescent.
In those days, she was prematurely burdened with the task of caring for her younger siblings so that her abnormally large household might function more smoothly.
These days, it seems Jana is still changing a lot diapers, but now she's doing it to help out her married brothers and sisters, not her parents.
Yes, to the surprise of absolutely no one "the Cinderella Duggar" is still working harder than anyone in the family.
Except these days, she's feeding and changing her nieces and nephews, rather than her brothers and sisters.
Yes, Jana has been spending a lot of time babysitting her siblings' kids in recent months.
Most recently, she logged some time with John David and Abbie Burnett's daughter two-month-old daughter Grace.
“Her parents think I come over to hang out with them," Jana captioned the above pic of her posing next to her newest niece.
She added the hashtag "#LoveMyNiece".
John David and Abbie were certainly grateful for the respite.
“Thanks to Aunt @janamduggar, Mommy and Daddy got a special evening out last night!” they captioned the above pic of their no doubt much-needed date night.
“Loved getting to watch Gracie!” Jana replied to the pic.
Naturally, the pic exchange led to speculation from fans who feel that Jana is being unfairly taken advantage of by her siblings.
Many suggested, that the situation might be particularly exploitative in this case, as John David is Jana's twin, and despite their closeness, there's always been a bit of a power imbalance in the relationship.
Basically, growing up, she tended to his every need, and he said thank you when he remembered.
The twins turned 30 last month, and Jana paid tribute to her twin on their birthday.
“It’s so sweet watching you & Abbie as parents! You’re naturals!" she wrote on Instagram.
"And the same qualities that have made you a wonderful brother will also make you an amazing dad. Being an aunt to your little girl is priceless. Being your twin is an honor.”
He wasn't quite as effusive in his praise of Jana -- in fact he didn't post anything at all.
But hey, we're sure Jana didn't mind.
And we're sure she doesn't mind caring for John David's daughter while he and his wife enjoy a night out.\
Still, it's not hard to see why fans might be concerned.
