Using survey data from mothers and guardians of children under 5 in rural Tanzania, this observational study found that fathers provide more direct/physical care to sons than daughters, while mothers allocate care equally regardless of child's sex.
Six forms of direct/physical care, resource provisioning, and breastfeeding duration were assessed by child's sex. Supplementary analyses found no interaction between child's sex and either child's age or birth order for care provision, and no evidence of sex-biased alloparental care from any of five alloparent categories. Limitations include reliance on survey data and potential social desirability bias.
