The Browns are having a tough time adjusting to their new life in Las Vegas. I mean, a move is hard for any family, but multiply that by 16 kids (with a 17th on the way) and four wives, and Kody Brown has got his hands full.

Watch our exclusive sneak peek of the new season (premieres Sun., Sept. 25, 9PM ET on TLC) and tell us what you think.
