Using a large-scale sample of online daters in eight European countries (N = 196,777), we examine willingness to stepparent among divorcees in relation to both gender and number of children, as well as a set of contextual determinants. We find evidence that having one’s own resident children increases the readiness to partner someone with children. Contrary to previous findings, women are generally less willing to stepparent than men, but when resident children are present, gender dissimilarities fade. Notable national differences are also found. Divorced mothers living in Sweden, the Netherlands, Austria, or France are more open to having a partner with children, whereas Polish and Spanish divorced mothers would be less willing to stepparent. These results are interpreted in light of each country’s institutional background.
