Hi, Skeeter. I found an AMA case study that references Prince v. Massachusetts.

Here's an excerpt.
It is distinctly more uncomfortable for them to report parents who clearly care for their children but hold personal, cultural or religious values that are at odds with those of the medical community [1,2]. There is a wide consensus in the medical profession and in the courts that even caring parents should not be allowed to refuse life- or limb-saving medications, transfusions, or procedures. Major difficulty often arises, however, in determining when the prognosis is sufficiently grave to warrant judicial intervention.
When parents hold a religious belief that leads them to refuse treatment for a child, at least 2 levels of understanding are needed in an effort to reach agreement. The parents need to understand the clinical situation as clearly as possible. This may sometimes be facilitated or augmented by obtaining a second (or third) opinion. It is ethically permissible to try to persuade the parents using honest facts and clear opinions, though it could be perceived as harassment if attempts at persuasion are frequent or authoritarian.
In addition, the health care professionals need to understand the religious belief as clearly as possible. These beliefs may sometimes be well understood and clearly articulated by the parents. It is often helpful, however, to involve a "religious translator" in the conversation, ie, a chaplain or perhaps another person from the parents' own faith tradition, and preferably a person with some depth of education and position of authority. One reason for utilizing such a resource person is that parents (or anyone) may sometimes focus on one religious tenet while ignoring a balancing tenet; eg, waiting for a miracle versus an obligation to preserve life and relieve suffering. A more objective look at the entire faith tradition may sometimes allow parents the freedom to consent to procedures without feeling they have abandoned the teachings of their faith.
Too often JW parents pin their hopes on "medical miracles" to pull their children out of a life-threatening situation. They need to understand that abstaining from blood transfusions can kill their child.
