The Browns just celebrated a big event in the family when episode 8 showed that Robyn's three kids from her previous marriage can now be legally adopted by the patriarch Kody.

In the previous episode titled "Chaos in the Cul-de-Sac," the unconventional polygamous family was busy trying to get things together to make the party a success. Along the way, there was indeed chaos as the sister wives could not seem to agree with their husband.

But first, the three kids — Dayton, Breanna, and Aurora — got their things ready as they headed for Montana to meet with their biological father, whom they had not seen in two years, according to Robyn.

In a confessional, Dayton revealed that he hoped his biological father would appreciate their visit rather than focus on some drama.

While the children were away, the polygamist family argued about what's to happen during the party.

Kody wanted to have a barbecue-style event, while Robyn insisted on having a dinner-style party, to which sister wife Christine agreed. Showing how the family argued over what to prepare for dinner only showed how much they value each of the family members.

Now that the three children have been legally adopted by the patriarch polygamist, the list of Brown children has grown, not to mention Robyn's upcoming child with Kody.

Will the new Brown baby be a boy or a girl? The next episode will answer that question.

In the next episode airing on Nov. 8, the Browns will be going to Alaska, with Logan's new girlfriend tagging along, as stated in the synopsis from TV Guide. 

The episode is also said to finally reveal Robyn's second baby's gender. Robyn initially thought that news about her second child with Kody will not be received well by the entire family. However, everyone was excited and happy about the little bundle of joy.

TLC has been keeping the fans guessing, but the next episode should finally make the big reveal.

A new episode of "Sister Wives" airs every Sunday at 9 p.m. EST on TLC.
