The high rate of under-five mortality can be an indication that the maternal and neonatal services are in alarm, boost immunity can reduce it. Immunity in infants can be obtained by exclusive breastfeeding. One of the factors influencing the success and failure of an exclusive breastfeeding is a working mother. In this work, we analyze the relationship between working mother status and exclusive breastfeeding by applying a semiparametric bivariate probit model. We also determine the factors that influence the working mother status and giving of exclusive breastfeeding. The data used are National Socio-Economic Survey (SUSENAS) data of Bangkalan 2016. Exclusive breastfeeding and working mother status as the endogenous variables but working mother status can be exogenous variable. Endogeneity causes the result in inconsistent or biased parameter estimation. Covariate-outcomes relationships can exhibit non-linear patterns. The parameter estimation method is penalized likelihood estimation. The resulting information is working mother status and exclusive breastfeeding have correlation, so it can be identified as the problem of endogeneity. The father's job has a significant effect on working mother status. Mother's education, father's education, father's job and working mother status as the exogenous variables have a significant effect respectively on exclusive breastfeeding.
