'Sister Wives' Family Welcomes 17th Child 29334

Robyn Brown, who is the fourth wife in the polygamist family featured on the TLC reality show "Sister Wives," gave birth to a healthy baby boy Wednesday, bringing the total number of children in the family to 17, reports.

The baby, named Solomon, is the first born to Robyn and husband Kody.  Robyn has 3 children from a previous marriage.

"He's perfect and we couldn't be happier," Kody tells PEOPLE. "We are so thrilled."

Solomon was born at home, 13 days past his official due date.

The Browns, who are fundamentalist Mormons not affiliated with the Church of Jesus Christ of Latter-day Saints, moved from Utah to Nevada last year after police launched an felony bigamy investigation last year.  In July, the Browns filed a federal lawsuit challenging the constitutionality of Utah's bigamy law.
