The purpose of this study is twofold: (a) to examine how women adjust their time allocation when they become working mothers; and (b) to assess the effect of their adjustment on their daily emotional experience. Using a methodology based on the Day Reconstruction Method which is designed to reduce systematic bias, seven women responded to a questionnaire during parental leave (T1), within 1 month after returning to work (T2), and 3 months after returning to work (T3). The results revealed that most of the participants tended to utilize the time available to them for sleep and child care by decreasing housework and leisure. They experienced increased pressure in terms of time and felt more or equally energetic or intimate toward their families in both T2 and T3. The other participants, who had less time available for sleep or meals, experienced increased depression or tiredness.
