On the most recent episode of Sister Wives, Robyn Brown told Kody she had visions of "a little dark-haired boy" and worried he was waiting for Robyn to birth him. This vision and Robyn's concern about not having birthed all her children seemed random to some viewers, but it's actually a very common belief in the Mormon religion. The existence of a "pre-life" is a fundamental tenet of the Mormon faith.

Robyn Brown grew up in a Mormon household in Utah and married a man from a powerful polygamist family, David Jessop. She had three children with him, including her oldest son, Dayton, who, as many viewers pointed out, has dark brown hair. Robyn is Kody's fourth wife and his only legal marriage. They have two kids together, Solomon and Ariella, who are both blonde. During Sunday's episode, Robyn and Kody tried to decide if they were done having kids or if they wanted another baby. Kody admitted he has been raising kids for 26 years and might be ready for a new chapter in life. He was torn, however, once Robyn mentioned her vision of a dark-haired boy who she thought might be her next child.

Robyn talked a lot about wanting to make sure she didn't leave any of her children behind by not giving birth to them. Robyn wasn't making up this fear – it's a common belief in Mormonism that before humans are born they experience pre-mortality, or the pre-life. Robyn is part of the Apostolic United Brethren church, which follows most mainstream Mormon teachings, with the biggest difference being their practice of polygamy, which mainstream Mormons don't believe in. Both the AUB and the Mormon church believe that before they are born, they exist in the pre-life as God's "spirit children." They believe the spirit children who promise to promote God's will on Earth are given a human body and sent to Earth.

As Mormons, Kody and his wives also believe they will be given as many children as they can handle, and that their children wait in the pre-life until they're born into a family. That's why Robyn, who many viewers consider Kody's favorite wife, was so concerned she may not be bringing all of her children out of the pre-life and onto Earth. Mormons also place great importance on dreams and visions, which they see as gifts from God – just ask Stephanie Meyer, whose Mormon perspective on dreams encouraged her to write Twilight after dreaming about a sparkling vampire in a field.

Mormon Elder Richard G. Scott summed up the belief in the power of dreams when he said, "One must be ever mentally and physically clean and have purity of intent so that the Lord can inspire. One who is obedient to His commandments is trusted of the Lord." Robyn believes her vision may be God's will, and that's why she feels such pressure to deliver the brown-haired boy she keeps envisioning. The question of whether she's done having kids or not isn't as simple as it would be for someone outside of the Mormon faith – after all, it's not just herself she has to consider, but her potential unborn children waiting in the pre-life as well.
