I saw online advice that assumed if you talk more it will lead to unity. Well, talking is the first step but if that doesn't lead to agreement, talking more will only lead to more disagreement. With parenting you've got to come together around a practical plan that you can implement. If you can't find agreement together involve a third party (the Bible, a person, a conference or a resource) that points you to what good parenting looks like. So, your talking moves you towards unity.
Talking about problems, is sometimes problematic.
