I don’t know the ins and outs of this specific case so my comment will be general but sometimes the family aren’t able to make the decisions that are in the best interests of the child - of course every parent wants to do what’s best and will clutch at every straw but sometimes it’s just not the right thing to do.
I suspect this is what is happening in this case, and taking the story on face value faith is a very strange angle to use as your argument. I suspect the Daily Mail are possibly sensationalising it a tad.
