This article examines the role of the sex composition of surviving older siblings on gender differences in childhood nutrition and immunization, using data from the National Family Health Survey, India (1992-1993). Logit and ordered logit models were used for severe stunting and immunization, respectively. The results show selective neglect of children with certain sex and birth-order combinations that operate differentially for girls and boys. Both girls and boys who were born after multiple same-sex siblings experience poor outcomes, suggesting that parents want some balance in sex composition. However, the preference for sons persists, and boys who were born after multiple daughters have the best possible outcomes.
