As addressed in the three prior parts of this series, the concept of intentionally planning to have a baby with a platonic co-parent raises many potential issues for careful consideration.

One might presume that a person who is considering entering into a platonic parenting agreement would prefer to enter into such an arrangement with someone they have known for a very long time, like a close friend with whom they have developed a long-standing history of mutual trust. Sometimes, however, a person subjectively wishes to co-parent with a partner with whom they have no detailed, deep-rooted past relationship at all—not even a platonic one. Often, this involves two people who have recently met online.
