The real problem for me has been getting my wife to change her perspective and parenting style. We've managed to remove spanking from our parenting as of this year, but getting her to remove emotional and verbal abuse is not easy, and ultimately is not something I'll be able to do. Watching her and her mother deal with issues, and having known her father, I can see why she has this approach to parenting...
My boys(7 and 4) are doing pretty well with more peaceful methods of parenting so far, the younger of the two especially. He's really coming around, but his brother will take much more time and a lot of work with mom. Younger brother has always been very empathetic, and considerate of other people's emotional needs. That's not always the case with property, but we're working on that =). He reacts much better to peaceful and rational parenting, and I'm sure that's especially the case being that we started it at a much younger age with him, compared to his brother. Also, I get more one on one time with him while his older brother is in statist slave training during the day time, which of course helps us bond and create better channels for communication.
Older brother has taken on much of mom's behaviors towards conflict resolution, which means that most of his conflicts involve lots of shouting, aggression, and passing around of blame. Working through this, with both him and mom, is incredibly difficult and usually ends up with stern looks and harsh words from mom, but I feel I must do the best that I can to help them communicate more effectively when conflict arises. He's very curious and loving, and I can tell that he's willing to learn and has no real desire to be evil or immoral, so I'm hopeful that with lots of work, we'll all be able to live much happier lives in the long run, by putting forth the effort necessary now.
