This has not changed since Dr. M. Sims' original paper. In Japan, where abortion has been legal and accepted for over four decades, a common custom is to conduct Mizuyo Kuyo services in honor of the god Jizo. This god has been made the patron saint of infants who died of starvation, abortion, or infanticide. Small baby statues, in his honor, are bought and dressed. Then, in a Buddhist Temple, rites of sorrow and reconciliation are carried out.
Children usually know that mother is pregnant.
This may cause Survivor's Syndrome, similar to that of Jews who survived the holocaust. Dr. Ney has written about this. Dr. Edward Sheridan of Georgetown University has observed also a fear and mistrust of the mother. Originally, a small child, sensing a sibling's arrival, doesn't welcome it. Or, if he knows that his mother was an active agent in doing away with the sibling, he begins to fear her.
