Abstract
This research was conducted as a self-reporting anonymous survey of 185 postpartum mothers in hospitals in order to clarify the causes of influence on the inter-child emotions of mothers, who are usually the main fosterers of the child. SPSS 12.0 J for Windows was used for statistical analysis, and the relationship between points of inter-child emotion and each questioned item was analyzed with Mann-Whitney U test and Kruskal-Wallis test. As a result, the following causes of influence on inter-child emotions were found : the existence of a key person, having a concrete birth plan during pregnancy, that it was a desired pregnancy, and that the mother was satisfied with her delivery. From this result, the following supports are thought to be important to realize : the importance of puberty education or contraception counseling, the establishment of a support system for mothers, and consistent support during pregnancy to postpartum at medial institutions where parturition is carried out.
