Research co‑author Aziz Sunderji shows American fatherhood has shifted dramatically. Millennial dads now devote more than 80 minutes daily to childcare—diapers, homework, sports—versus just half an hour in 1965. To free that time, fathers cut an hour of office work and trim TV by 30 minutes, reshaping daily routines across the United States for their growing families.

Scholars trace the surge to women’s mass entry into paid labor, which left a childcare gap fathers began filling. Yet mothers’ own time rose, disproving a simple substitution model. Data from the American Time Use Survey reveal that the increase is driven chiefly by college‑educated fathers under 45, whose childcare grew from 9 to 46 minutes more than less‑educated peers in recent surveys as well.

Beyond economics, researchers argue that affluent dads treat intensive parenting as a status signal, investing time to boost children’s future school prospects. This cultural shift turns childcare into a form of leisure and prestige rather than mere duty. The data therefore illustrate how evolving gender norms and class attitudes have reshaped the American dad’s daily agenda among middle‑class households.
