At the start of season 15 of Sister Wives, Janelle’s daugher Maddie Brown Brush and her husband Caleb Brush debuted their daughter Evangalynn, who is called “Evie” for short, to Maddie’s siblings and the show’s audience. They did a bit of an unveiling by pulling a blanket off of the baby carrier to show the wide-eyed beautiful little girl, but they had to offer some education as well. Evie has been diagnosed with FATCO syndrome, which is a “congenital limb malformation syndrome,” according to Orpha.net.
