This study examined whether the frequency of child-related activities was associated with parents' own work demands and those of their partners. In addition to parental paid working hours, we considered the parents' organizational culture and experienced job insecurity. Moreover, we differentiated between child-related routine and interactive activities. Using self-collected data on 639 Dutch couples with children, we found that paid working hours were consistently associated with a lower frequency of child-related activities. Fathers generally responded more strongly to their own and their partner's work demands than mothers. For fathers, both their own and their partner's work demands were more strongly associated with routine than with interactive activities. Mothers did not differentiate between these activities, however.
