Early childhood education and care (ECEC) has been found to be beneficial for the development of children below three years. However, many children do not attend ECEC facilities. Frequently, structural family characteristics (SFC), such as migration background, educational attainment and income, are used to explain differing probabilities of attendance, while parental attitudes are mostly not considered. Thus, assuming that SFC influence attitudes, this paper investigates whether the attitudes and views of parents towards ECEC explain why one- and two-year-old children from disadvantaged families attend day care less often, although they would strongly benefit from high-quality ECEC. The underlying data are from the German DJI Child Care Study (KiBS). The results show that parental attitudes substantially contribute to explaining diverging attendance probabilities. The more positive parents evaluate day care, the higher the probability of their child attending. However, SFC maintain most of their explanatory power. Besides, SFC and parental attitudes interact. The probability of ECEC attendance increases differently depending on the (varying degree of positivity of) attitudes by SFC.
