As I continue to share the common list of co-parenting challenges, the next one on the list is, âThe handling of schedule changes and lack of flexibility and adaptability.â This co-parenting challenge is very common and almost always a direct result of anger and emotion attached to separation and or divorce. Regardless of your custody or visitation schedule, you will find, at some point in your co-parenting, the need for flexibility and adaptability. It is so important to remove anger and emotion. If you are the parent needing or requesting a schedule change, or if you are wanting some flexibility, the need and or the request will be better received if you have not created high conflict in your co-parenting.
