The Korea government has implemented various policies for supporting child care. Although most policies are direct supports such as financial aids and providing services, parents who raise young children need a substantial amount of time to be with their children. This study, therefore, adjusts a focus on policies of securing child care time, and then finds how these policies are performing by the survey on either mother or father from the double income household. Based on the survey, the study analyzes which factors affect a decision on child care hours using ordinary least squares (OLS) method and negative binomial regression (NBR) model. According to the survey, 40 percent of mothers and fathers have experienced an increase in child care hours by using flexible work time policies. And more than 50 percent of them reply that their company implements leave policies, but it is hard to use policies when they need them. In addition, many respondents answer that they have experienced disadvantage at the workplace after using flexible work time policies or leave policies. The reducing work time policy for child care increases by 1.20 hours of mother’s child care time using model 4 with OLS method, and as using NBR model, more flexible work time policies and leave policies influence an increase for child care hours. For fathers, relatively various policies affect an increase for child care hours from both analyses. To narrow the difference between policy demand and utilization in the future research, the survey on the demand and utilization by employees and employers should be performed at the same time. In addition, to encourage the father’s participation in child care, policy-makers recognize that different factors between mothers and fathers affect a decision on child care hours.
