Data were collected using self\u2010report questionnaires on the day before hospital discharge. The questionnaire consisted of: demographics and background information; depressive symptoms; fatigue; maternal confidence and maternal satisfaction; child\u2010care values; physical symptoms; perceptions of daily life during hospitalization; concerns about child care and daily life; and infant feeding. Additionally, vital records data were obtained from the hospitals.
