The Brown family is about to get much bigger with a new baby on the way. Robyn is pregnant with her second child with Kody and the 18th in the family. In "Sister Wives" season 6, she made the announcement and she did so with nervousness.

Apparently, Robyn is scared that the reaction of the family will be the same as the time she revealed she was pregnant with her and Kody's first kid – unconcerned. But to her surprise and delight, her pregnancy made everyone "happy and excited."

Unfortunately, Robyn is yet to reveal if the baby will be a boy or a girl. There were even speculations that she will be having twins. But right now, TLC wants to keep "Sister Wives" season 6 viewers guessing and the excitement and curiosity growing.

Noticeably, Robyn is on to a lot of familial endeavors. At the moment, she and Kody are close to winning their battle for the custody of the former's three kids in her previous relationship. The pair is literally a Nevada judge's signature away.

However, this step, although it puts them at the closest they have ever been in the whole duration of the process, isn't the quickest. Wife no. 3 Christine thinks that winning over a judge who "thinks polygamy is a terrible thing for children" is no easy feat.

Speaking of Christine, Kody and her have been in several therapies as seen in previous "Sister Wives" season 6 episodes. Christine wants to let her husband know that she understands that they may disagree at times but she still hopes that beyond all that, Kody still loves her.

Meanwhile, in the next episode of "Sister Wives" season 6 airing 9 p.m. ET on TLC on Oct, 25, viewers will be treated a peek of the dating life of Kody and Janelle's 19-year-old daughter, Maddie.
