'Sister Wives' season 7 spoilers: Meri and Janelle attend therapy to repair broken friendship, end up clashing

"Sister Wives" season 7's most recent episode showed Kody Brown dishing out on wife Robyn's difficult pregnancy. Meanwhile, the upcoming episode will have Meri and Janelle attending a therapy session, supposedly to repair their broken relationship. They end up clashing in the process.

Ariella Mae Brown, the youngest of Kody's 18 children, was born sometime in January, but it was only last Sunday when the Brown family patriarch shared details on Robyn's near-fatal delivery. According to Design and Trend, they found out that the baby's head had not turned down yet very near her delivery date.

Normally, an unborn baby's head turns down between weeks 30-36 to prepare it for birth. Otherwise, it would be too risky for the baby and the mother.

It's a good thing little Ariella's position changed a few days before she was born, so Robyn was able to give birth without further hitches. A photo shared by Robyn on Twitter shows a healthy Ariella being cuddled by her older brother, Solomon.

Meanwhile, Us Weekly said the June 12 episode of "Sister Wives" season 7 would see Meri and Janelle Brown sitting down with a therapist in an effort to repair their rocky friendship.

In a video clip for Sunday's episode, 45-year-old Meri said she and Janelle have tried ironing things out between them by "working on Thanksgiving decorations together," but apparently, they organize table centerpieces "completely different." Meri feels such difference serves to injure their already fractured relationship further. Check out the video below.

"We also have years of reacting to each other's differences," she said in the clip. "We have that added on top of it."

Fans would recall that Meri and Janelle's problem with each other go way back, specifically ever since Janelle ended her previous marriage with Meri's brother in order to marry Kody.

"Meri and I went from cordial to frosty overnight. We snipped at each other over the smallest things," Janelle wrote in the book "Becoming Sister Wives: The Story of an Unconventional Marriage."

Hollywood Gossip hopes that Ariella's birth and the family's upcoming Hawaii vacation would finally unite the polyamorous family and help them move on from personal differences and catfishing scandals.

"Sister Wives" season 7's next episode will air on June 12 at 8 p.m. ET on TLC.
