She’s here! Sister WivesRobyn Brown welcomed her second child, a baby girl, with husband Kody on Sunday, January 10, TLC confirms to Us Weekly. The reality stars are already the proud parents of a 3-year-old son, Solomon.

The couple’s little girl was born at 10:10 p.m. on Sunday and weighed 9 pounds, 9 ounces, measuring 21.5 inches long.

The bundle of joy kept her mom on her toes prior to her arrival. “Two days away from my due date. We are all ready to meet Baby Sister! Trying to be patient but can't wait to see her sweet face,” Robyn, 37, tweeted on January 5, updating fans three days later on January 8 that she was past her due date. “When is this little girl going to come?” she pondered. 

Kody’s polygamous family includes three wives — Robyn, Christine and Janelle — and a total of 18 children now. Robyn, who legally married Kody in 2014 following his divorce from Meri, is also mom of three other children from a previous marriage.
