Jen and Patrice talk about shifting parental duties post-divorce. What happens when both parents become the "default" or "primary" parent?  Co-parents can't plan for every parenting contingency, but good communication channels can make a huge difference in how the unexpected (and the expected) play out. Mediation and collaborative process provide effective means for parents who are shifting into co-parenting roles. Parents can explore options in communication and duty sharing before committing to something that might not be livable.
