Since many nursing students struggle to understand the psychology of the puerperium, we clarified how to understand the worries of the puerperium through semi-structured interviews. As a result, they were able to understand their worries by ``reading their psychological state from the behavior of the puerperal mother and their interactions with the nurses,'' ``determining the degree of worry in relation to their experience of giving birth,'' and ``reluctance to listen because of their sense of burden.'' "I don't know how to listen to her worries." is not fixed.” It was suggested that teachers need to understand the feelings of students who are worried about giving them a psychological burden and give advice and guidance on how to interact with them.
