Our event study analysis uses Belgian data to show that the incidence rate of disability across gender only diverges after first-time childbirth. This “other child penalty” can be reduced with the provision of paternity leave. Our regression discontinuity difference-in-differences design shows that mothers with partners eligible for a two-week-long paternity leave spent on average 21% fewer days on disability over twelve years. Moreover, we show links between this incidence of paternity leave and consequent birth-spacing decisions.  \nJEL Classification: J16, J13, I13, H55  \nKeywords: disability insurance, gender, child penalty, paternity leave,  \nmaternal health, birth spacing, natural experiment, regression discontinuity, event study  \nCorresponding author:  \nIlan Tojerow  \nSolvay Brussels School of Economics and Management Avenue F.
