This study examines the factors that influence choices made for education and child care services for infants and toddlers, focusing on varying costs according to the types of education and childcare services or various combinations of the services. The data used in this study were pooled from the data of the research on the Estimated Infant Education and Child Care Costs (IV) to (V) done by the Child-Rearing Policy Institute, and the number of subjects was 3,325. The analytical model used was a multinomial logit analysis and the Heckman sample selection model. As a result of the analysis, it was shown that the total probability of using education and childcare services increased as the age of a child increased. According to the types of service, the total cost of education and childcare for families of infants and children using daycare centers was significantly lower than that for those that did not use daycare centers. On the other hand, after correcting for sample selection convenience bias on the use of education and childcare services, determinants of the education and childcare costs for each service were examined, and the results showed a significant difference depending on the types of services. In particular, household income did not have a significant effect on the cost of using a daycare center, but the costs of using hourly private tutoring as well as individual care services were significantly higher for higher household income.
