Hi, delay in posting as I've been away.
The only post mortem reports I've seen relating to stillborn babies give date of delivery, type of delivery etc and very full details of all the organs of the body including the skin, the state they were in, the size and weight and any abnormalities, to try to ascertain cause of death and the time of death, but they don't give any info about what happened to the babies after that. I guess, each stillbirth is different. Some parents will want to take their babies and have a funeral and burial, others will just leave the baby with the hospital for the staff to deal with.
