I stopped watching when Kate told the kids they didn't have to listen to/do what Daddy says because he is mean.

Nice way to undermine your partner! You don't have to agree with what they're doing (and believe me, in this case it wasn't anything serious), but deal with it in private, NOT in front of the kids. I hope the money and fame are worth the problems she's going to face in about 10 years with those kids.
