The present study aims to investigate several relevant psychological factors, including both mother characteristics (i.e., basic psychological need satisfaction and frustration, depressogenic personality) and child characteristics (i.e., infant temperament) in relation to daily variation in maternal well-being. Mothers (N = 126) participated in a five-day diary study shortly after child-birth, when the child went to day-care for the first time. The latter specific episode was chosen as this period is potentially stressful (due to parent–child separation and challenges in work–family life balance) and within-person variation is expected to be high in such episodes. At the within-person level, day-to-day variation in psychological need satisfaction and frustration related to day-to-day variability in maternal well-being. At the between-person level, maternal self-criticism related negatively to well-being, while perceived infant temperament yielded few direct associations. Instead, the child’s temperament played a moderating role in the association between basic psychological needs and maternal well-being. The findings of this study underscore the importance of a dynamic view on maternal well-being, with basic psychological needs, maternal personality and infant temperament contributing to well-being in a complex fashion.
