We investigate the impact of maternity leave on the cognitive and behavioral development of children at ages 4 and 5, following up previous research on these children at younger ages. The impact is identified by legislated increases in the duration of maternity leave in Canada, which significantly increased the amount of first-year maternal care. Our results indicate no positive effect on indices of children’s cognitive and behavioral development. We uncover a small negative impact on PPVT scores.
