In order to count in the "Counting On" Duggar Family, you have to either be married, courting or one of the "19 Kids and Counting" under 12, it seems. Case in point is Jana Duggar [VIDEO] who is left out of so many adult sibling activities except as the DB (designated babysitter). The eldest, single daughter incensed fans being relegated to kid care at the wedding of Joe Duggar and Kendra Caldwell when even Anna and Josh Duggar got to join the grownups. But she was also absent in birthday wishes to Michelle Duggar.

Has the girl finally had enough of playing mom?

Where's Jana Duggar?

That young lady is harder to find than Waldo in "Counting On" activities lately. Reality TV viewers didn't even realize that Jana went along on a trip to visit Jinger Duggar Vuolo and Jeremy Vuolo in Texas.

"Counting On" cameras only showed Jessa Duggar Seewald and her husband Ben Seewald. Even their little boys weren't filmed much. Then Instagram and Duggar family official Facebook pics showed Jana Duggar and a girlfriend with Seewald kids in tow. Was she only along for to play nanny?

Jana does kid detail Joseph Duggar's wedding?

"Counting On" will air the rather hurried wedding of Joseph Duggar and his child bride Kendra Caldwell, 18. Like Joy-Anna Duggar and Austin Forsyth, that pair was supposed to be married in the fall. But they jumped the gun like the Forsyths who were wed in May. Joy-Anna was even sporting a curiously large baby bump at her sibling's late summer wedding. Michelle and Jim Bob Duggar proudly showed all the married "19 Kids and Counting" adult celebrities. But no Jana or her twin, John-David.

The 27-year-old daughter did share a selfie with all the little kids.

John-David Duggar to wed, what about Jana?

There's a rumor that the very-private John-David Duggar may be courting and fans are wondering where that leaves Jana. The "19 Kids and Counting" boys have some kind of training. They are allowed to stay single longer. But the Duggars wed and bed the girls young. So Jana's in no-man's land, literally. Male or female, though, reality television seems the "Counting On" family's biggest occupation. Jill Duggar Dillard's husband Derick Dillard is unemployed and had to start a charity fundraiser to pay for a Bible class after quitting his self-styled missionary work.

Jana misses Michelle Duggar's birthday

Jana Duggar was also conspicuously absent from Facebook and Instagram birthday wishes to Michelle. All the married kids, Josh and Anna Duggar, Jill, Jessa, Jinger, Joy and their spouses sent greetings. The "19 Kids and Counting" little ones sent a group greeting, with the help, no doubt, of Jana. But she didn't join her twin in wishing the "Counting On" mom HBD. Is the Reality TV celebrity sending a message that she's tired of doing her mother's job? Or was she too busy taking care of her siblings, again?
