I am finding it really hard to talk about parenting issues with my best friend. The two of us never seem to see eye-to-eye on anything that has to do with our kids. I’m worried that this is going to destroy our friendship.
It sounds like you and your friend may have reached a crossroads in your relationship. It may be that you have both changed so much so much since you had kids that you no longer feel like you've got much in common. After all, if you can't talk about your kids—a really important part of your life—it may be difficult to connect with your friend on any meaningful level.
If, however, you've been friends with this person forever and you feel that the relationship is worth working on, you may decide to focus on the things that you do have in common and to agree to disagree on parenting issues (or to avoid discussing parenting issues altogether).
It's worth remembering that it's quite normal for our circle of friends at one stage of our lives to be quite different from our circle of friends a different life stage. After all, what we look for in friends changes as we change. And few things change us in more profound and lasting ways than the experience of becoming a parent.
