Research studies and popular accounts of parenting document the joys and strains of raising children. Much of the literature comparing parents to those who do not have children indicates a happiness advantage for those without children, though recent studies unpack this general advantage to reveal differences by the dimension of well-being considered and important features in parents’ lives and parenting experiences. We use unique data from the 2010, 2012, and 2013 American Time Use Survey to understand emotions in mothering experiences and how these vary by key demographic factors: employment and partnership status. Assessing mothers’ emotions in a broad set of parenting activities while controlling for a rich set of person- and activity-level factors, we find that mothering experiences are generally associated with high levels of emotional well-being, though single parenthood is associated with shifts in the emotional valence. Single mothers report less happiness and more sadness, stress and fatigue in parenting than partnered mothers. This is concentrated among those single mothers who are not employed. Employed single mothers are happier and less sad and stressed when parenting than single mothers who are not employed. Contrary to common assumptions about maternal employment, we find overall few negative associations between employment and mothers’ feelings in time with children, with the exception that employed mothers report more fatigue in parenting than those who are not employed.
