I'd like to think that it would be possible for parents to simply take their child out of a hospital, but there might be situations in which that would not be possible. For instance, I think that medical staff could call Child Protection Services if they thought that the parents were not acting in the best interests of the child. There would be a strong chance that parents would immediately lose custody of the child, and any voice in that child's care. They would have to explain why their actions were not abusive, ie. neglecting the medical needs of the child. The parents would then have to hire a lawyer and prove they are fit to have custody of their child, and might have to agree to follow protocol laid down by CPS agents. (I'm referencing the current situation happening with BCH which may not be correct for this thread. Mods please snip if needed.) Could someone with more direct knowledge about this question correct any errors in what I've written? I think it's a really interesting point. Thanks.
