The Brown family is officially whole! The “Sister Wives” clan legally welcomed Robyn’s children -- Dayton, Aurora and Breanna -- into the family during Season 6 of the TLC series after a judge granted Kody, the patriarch of the polygamist family, guardianship over Robyn’s three kids from her previous relationship. Now the ladies of "Sister Wives" are speaking out about the emotional adoption, which was finalized on June 12, addressing both the ups and the downs that occurred throughout the year-long process.

"Usually when a plural family goes into a court room they are tearing apart a family so we were really nervous going in," Kody’s now legal wife, Robyn, told People magazine, explaining the difficulties polyagmists face when it comes to adoption due to their controversial lifestyle. Kody previously bolstered that statement in episode 7 when he also stated his fear of his plea getting denied.

“[The adoption is] so vital to our family,” Kody said on his TLC reality show. “It’s so important, but we don’t know if it’s going to happen.”

But surprisingly enough, the judge approved the adoption, naming Kody as a legal parent of Robyn's three children.

"But here we were the whole family and we were uniting our family. It was really cool for us. Very much a validation of our family," Robyn added, explaining how the family felt after the judge's exciting ruling.

However, the adoption wouldn’t have been possible without Kody’s first wife, Meri, who relinquished her 24-year title of being Kody’s legal wife so that Robyn could become Kody’s spouse in the eyes of the law.

“It was a really sweet offer and, as far as polygamous relationships go, I don’t know of any other family that has done this where another wife has given up a legal marriage so he can marry another wife and that way they can adopt the kids,” Christine, Kody's third sister wife, spoke of Meri’s selfless decision to divorce Kody. “This isn’t something that happens so it was really sweet and generous.”

But Meri told People magazine that she knew that the structure of the family would have to change in order for Dayton, Aurora and Breanna to become Browns. "That was something that I decided to do just for the purpose of the kids. And the adoption, it was something that I knew that they wanted to have their legal name Brown. They really wanted to be adopted,” she stated.
