I, too, agree about maintaining custody. I have full, but H can see them whenever, which is about once a week. Mine are older, but agree that the less disruption the better. As a teacher, we always know which kids are in 50/50 and which is the better parent lol. It is very disruptful in all aspects of a child's life. That being said, it can work if the mother and father have a great relationship and a ton of communication and desire for only the best possible outcome for their children.
