"Positive discipline for Single Parents" by Nelson, Erwin, and Delzer
(I don't know if any of you remember me. I still lurk sometimes.)
I am also having a lot of discipline problems with my children now. I am the bad guy and my ex has sabotaged my authority with them. I am starting both children with individual counselors so I hope that helps. The book I mentioned has also been helpful. I implemented the family meetings that they recommend and I think it is helping. Good luck!
