There are times when my husband and I contradict each other's parenting methods. What's a good way to resolve such issue, aside of course from talking with him?

Why not give both your methods a try and see which one the kids respond to better? Don't do it simultaneously as this will confuse the kids but maybe take turns doing them for a week each. Growing up, I found that I would be more inclined to listen to my parents when both of them "team up" as I would have no one to negotiate with haha. Find common ground in your parenting styles and appear as a unit. Nothing drives a point across better (for me at least) :)
