"Sister Wives" season 7 is all but confirmed by TLC but there are already a lot of speculations about the upcoming season of the reality series following the Brown family. Word on the street is that it will be all about Kody and legal wife Robyn's new baby.

Robyn is expected to give birth to her and Kody's second child (and the 18^th in the family) by January. The new little one will apparently be the center of the new season as well as the pair's life with Kody as the new legal father to Robyn's three other kids in her past relationship.

With this, fans are starting to wonder what the rest of the wives Meri, Janelle and Christine will be up to in "Sister Wives" season 7. Season 6 barely gave them enough room and reports say that no big storylines about them will be tackled in the new season.

In the previous season, Meri was heavily featured. The season followed the former legal wife's journey before and after divorcing Kody for him to be married to Robyn instead and eventually get greater chances to win the legal custody battle, which they did.

It was the loneliness that came with this decision that apparently sent Meri seeking for attention. This ended with a heart-rending catfishing scandal she opened up about in the special tell-all episode. Meanwhile, Christine's chunk of exposure was her struggle about her and Kody's lack of intimacy.

At the moment, TLC is yet to talk about "Sister Wives" season 7, although host Tamron Hall, who facilitated the tell-all installment of the last season, has already teased via her Twitter account that it will have something to do with the new baby.

Whether or not "Sister Wives" season 7 will be more about Robyn and Kody than the extended family remains to be seen. A premiere date for the new season is yet to be determined as well.
