Well, I hate to sound like a broken record, but we have similar issues in my household, as well. We have been married for 2 years, and together for four. We are raising my 11 and 13 year olds as well as our 2 month old. Of course, we aren't having problems with the baby, but disciplining the older kids is a constant source of disagreement for us. My husband is finally starting to see that his way doesn't work, but it has been a really slow transformation. He did spank the kids in the beginning, but hasn't done that in a long time. Now he lectures and hands out groundings, which I have said over and over don't work. He finally bought "positive discipline for teens" a few weeks ago, and I am hoping we can read it together and adopt some of the principles together.
The advice that I would give is to try to find a book, or possibly a book on CD if your husband doesn't like to read. I think it would be best if you could agree on a strategy, maybe look for a book together, and use a strategy that you can both live with. My experience has been that it's really hard to get your spouse to see everything your way, but if you can both compromise, it should work out. Just don't wait till the kids are teens like my older ones are!
