There seems to be different stories, the transcript you put on had the baby being stuffed head first into the grave alive, then an American article (losing it here)had the baby with a feeder by its side.
The concentric circles of wooden stakes was weird round the grave, I wondered if it had anything to do with keeping wild animals out as well.
As for Hamish's youtube film, its X rated or something, you have to sign on.
All in all, Chinese politics, American filming, gives a somewhat distorted view and still no pictures of so called sheela-na-gigs, though the cave art seemed to reflect a northern Scandinavian touch?
