Four things that help my ex and I happily co-parent

We are both kids from divorced families, and we both realized that we should both be equally and amiably involved in our daughter's life to raise a happy and secure child as best we could with the circumstances. We take her to dinner together a few times a month, spend holidays together, and try to make sure she knows that even though we are in two separate houses, we are still a family and still her mommy and daddy.
