In a prospective study 81 randomly selected parents awaiting their first baby were interviewed early during pregnancy and again during the week after delivery. About 80% of the women and their partners were found to hold their child to the left, and 20% to the right, irrespective of handedness. There was no relation between side preference in child holding in the couples. Common to both sexes is the trend that left-holders are more attached to and identified with the parent of their own sex whereas right-holders are more attached to and identified with the parent of the opposite sex. Right-holders have also more often had mental symptoms prior to pregnancy and were concerned about the pregnancy, delivery and health of the child at birth.
