To me this looks very much like a PM photo, and as morbid as we may think it was, it was commonplace and helped the families grieve. Aside from her eyes, her feet look "planted" and also the curtain does not have a natural drape as there is bulge behind the child which suggests to me that someone or something is supporting the child.
I have seen many pics with the deceased propped up using posing stands.
