Their family is due to get bigger, and now, the Browns will learn if their newest addition will be male or female on Sister Wives.  

Meri Confesses The Truth About Being Catfished

On the November 8 episode, the entire family will take a trip to Alaska, where Kody and Robyn will finally reveal to the rest of the family whether or not baby number 18 will be a boy or a girl, answering the one question that has been on everyone's minds since the pair announced they were expecting.

Thus far, the 24 members of the Brown family tend to skew in favor of females, with wives Meri, Janelle, Christine and Robyn helping daughters Aspyn, Mariah, Madison, Mykelti, Gwendlyn, Aurora, Ysabel, Savanah, Breanna and Truly keep their numbers higher. The men consist of Kody and his sons Logan, Hunter, Paedon, Garrison, Dayton, Gabriel and Solomon.

The Adoption Party Plans Go Awry

However, before the big reveal, the family will need to prepare for the many meals they will consume during their trip, with a huge trip to the grocery store that includes all 24 members. In a preview clip for the episode, the trip proves to be chaos as the group descends on the supermarket with plans for each wife to tackle specific parts of the grocery list.

"Each mom is in charge of getting certain things," Robyn explains in the clip of the over 500 meals they have to buy food for. "Like I'm in charge of getting all of the stuff for the sack lunches, Christine's in charge of a lot of the breakfasts, Janelle is taking a couple of dinners, Meri is taking a couple of dinners, I'm taking care of a couple of dinners. That way, we're not buying the same things."

Sister Wives airs Sundays at 9 p.m. on TLC.
