Yeah, it appears there's nothing they can really do for it, aside from just watching it (and it's probably a once in a lifetime kind of thing, so a lot of interesting medical stuff could be learned from it). But without the parents' permission there's not much they can do.
This has happened a fair few time before, eg:
Mother Sushma holds her daughter Lali at their residence in Saini Sunpura, 50 kilometerseast of New Delhi, India.
this is Lali from Saini Sunpura, 50kms due east of New Dheli, India
I can't fin musch on humans but from what I can find out on craniofacial duplication in animals doesn't look to promising. Many two-faced animals don't live long due to the resulting internal organ and brain abnormalities. One problem for this child would be the dual oesophagus and trachea.
