This research explores how parents modify their attitudes towards gender norms following childbirths. Using longitudinal data, I observe that parents become more traditional in their views: they put higher emphasis on family and on division of household roles. To understand why this is the case, I explore differences across countries. I find that changes are more prevalent in countries with lower access to formal care, higher division of gender roles and low involvement of husbands in household duties. In short, parents modify their attitudes in those countries where it is more difficult to reconcile work and care responsibilities, and where traditional role models were more available. In the poster there is a link to the working paper version of the paper. Any comments and suggestions are welcome
