Another happy milestone has come for the Brown family from TLC's Sister Wives, with the first official wedding of one of the family's children over the weekend!

Madison "Maddie" Brown, the eldest daughter of Kody and his second wife, Janelle, officially married fiance Caleb Brush on Saturday, June 4, in Bozeman, Montana, marking the first wedding of one of the family's 18 children.

The Bohemian-themed ceremony, which the couple held outdoors, came after months of planning, and was something the bride could barely wait to have happen, as evidenced by some of her posts on Instagram in the weeks leading up to her nuptials.

In addition, Brown's father was the officiant for the ceremony, according to Us Weekly. She also had five bridesmaids, but it is unclear if the 20-year-old asked any of her sisters to be among them.

However, while the news of her nuptials seems to be happy, not every member of her family shared news on social media of their happiness about the event.

While her mother shared photos of Montana itself and also took to Twitter to update fans that they wouldn't be live-tweeting the June 5 episode of their show, the only other adult to share anything related to the wedding on social media was Meri, who shared a loving message for Maddie and Caleb.

"Beautiful day for this beautiful bride & her amazing new husband. Love these two!" She wrote.

However, Kody, Christine and Robyn were all silent about the wedding on social media, not sharing any update of their own or their wishes for the newly married couple. It is unclear if their lack of posts have anything to do with feelings about the wedding, or if they actually just haven't shared anything yet due to an inability to sign on and share a congratulatory message.

Sister Wives airs Sundays at 9 p.m. on TLC.
