I don’t get why a child like this is in school anyway. What can she gain from it? If the point is to give the parents some respite from caring for her, there are other ways to accomplish that.
I am a recent highschool grad and can say that all through my school years severly disabled children who were baisically in a PVS were in school. The schools have become a way for parents to get a break from their kids.
i cannot speak for this particular case but i do know that my mother volunteered at the public school in my old home town to work with brain injured kids - some apparently as bad off as this. The teachers try to (and you will forgive me if i am not using correct terminology) have the kids “remember” motor functions doing numerous exercises and other such things. I visited her there once and it is so heartwrenching. Now again i dont know about this particular case however sending a brain injured child to school is not unheard of.
Given the DNR I would speculate that the child is in school so that the parents do not have to deal with her at home and they can get someone else to put her down and relieve their lives of the “burden.” They have the vestiges of conscience in that they want someone else to be the agent but it is only the tiniest trace.
