INTRODUCTION: The integration of theoretical material in the classroom with clinical practice in the field is an important concept in nursing education. Nursing students at all levels need to acquire individual patient's needs, and applying creativity in the comprehensive nursing care. Problem solving and observa- tion skills are important aspects in the development of nursing skills. Nursing students during their clinical work in maternal and child health observed that the major difficulties experienced by new mothers centered around psychological and physiological changes. Breast engorgement and thorbbing breast pain were the most frequent complaints by primiparas during the postpartum phase. In order to understand the factors affecting the discomfort, and to devise appropriate nursing care, these complaints were experimented. resent study represents an attempt to ewaluate the impact of antepartal care(including breast care)on the subsequent of breast feeding difficulties. For the research purposes, hypotheses were made as follows: 1. There is a relationship between breast care and antenatal care attendance. 2. If primiparas pracitce breat care during their antenatal peried, they will have less throbbing breast pain during the postpartum phase. 3. If primiparas practice breast care during their antenatal peried, they will have less breast engorge- ment during the postpartum phase. METHOD: The researcher selected two highly specialized nurses in maternity clinical ward. They checked mother's chest circumference on the top line of breast every morning including mother's fever, caked- breast, end lymprmedes on axillae. These nurses checker] mother's breast while they staying hospital for four days. The total number of primiparas were 62 during June 5th to July 15th in 1971 at the Severance Hospital. For 40 days among 62 members of new mothers, 28 of them had breast care during antenatal period. Rest of them did not have breast care during antenatal period. RESULT: The result of this research revealed that the first hypothesis was accepted that the group which had breast care during antenatal period, had positive relationship with antenatal care. If the mothers were more educated, the more anticipated to antenatal care including breast care. For the second hypothesis, on the delivery day, there was no change on breast between two groups, On the first day of delivery, there were breast throbbing pains to the group who did not receive breast tare, than the group who received the breast care. Therefore, second hypothesis was also accepted. For the third hypothesis, there was no breast engorgement difference between two groups for the entire period. The third hypothesis was rejected.
