I've been thinking about this, and I wonder whether there is actually an element of conflict between the disability and the medical needs.
It is unthinkable to suggest allowing a disabled child to die and rightly so. Because disabled children can and do grow up to have fulfilled happy lives, and quality of life with a disability is subjective because what to one is unbearable is a fulfilled life to someone else.
But take the disability out of the equasion and concentrate only on the medical needs, and suddenly the thought of allowing that person to die doesn't seem so horrific.
If a mother watches her child go through years of painful and agonizing treatments and surgeries knowing that that child will die in the end, is it unreasonable of her to think that perhaps it would be better for that child to have a peaceful death now, rather than going through years of pain to prolong the inevitable? Tbh I'm not so sure that it is.
Is our judgement perhaps clouded by the disability thus leaving us unable to see the real plight of the child? If the child had been born without the disability but unable to breathe, would we be so quick to say he shouldn't be allowed to die in peace? I'm not sure.
