Sister Wives stars Kody and Robyn Brown welcomed their first child together on Wednesday, according to People. Solomon weighed in at 9 lbs, 10.5 oz., and is 22 inches long. “He’s perfect and we couldn’t be happier,” Kody tells the magazine. “We are so thrilled.”

Solomon is Kody’s 17th child — three of which are Robyn’s children from a previous marriage. The practicing polygamist has three other wives, and he married Robyn during last season’s finale of the TLC series. The entire clan recently moved to Nevada from Utah after that state’s police began to investigate the family’s lifestyle.
