First, focus on your parenting goals. For example, most parents want to have a good relationship with their child even when he or she is an adult. Ask yourself if your discipline methods help in this effort. If not, then it's time for compromise.

Second, gain parenting skills together. Seek out independent research-based parenting support such as a Positive Discipline parenting class. Or read John Gottman's book, Raising an Emotionally Intelligent Child, which promotes the idea that parents would do well to cultivate their parenting base of power with respect rather than fear.

Lastly, work on what you do agree on. Consider what happens when two people are each holding an end of a rope. Most of the rope is in the middle and represents those things that you have in common, so there are more things that you agree on, than what you disagree on. Build on what you have in common.
