Social norms, market imperfections and the structure of the labour market may limit women’s labour market opportunities in low-in- come contexts. While access to childcare has been critical for mothers’ labor supply in many high-income countries (Baker et al., 2008; Gelbach, 2002; Goldin, 2021), it remains an open question whether it can improve maternal labour market outcomes in low-in- come settings and how it affects other household members. We present findings from a field experiment that we designed and implemented in Uganda to understand the impact of free childcare on the mother’s business development and labour supply. More- over, we add to the literature by also considering the impact of childcare on the labour supply of other household members, as well as a range of outcomes related to family welfare, including child development.
