Objective In this study, we analyze breastfeeding and weaning practices in pre‐Columbian complex hunter‐gatherers from the lower Paraná River basin (South America). Materials and Methods We carried out bone isotope analyses concerning δ 13 C in collagen and apatite, the spacing between both carbon sources and δ 15 N in a sample of 23 subadult and adult individuals of both sexes recovered from Late Holocene archaeological sites, ranging from 1665 ± 45 to 680 ± 80 14 C years BP. Results and Discussion The results indicate that exclusive breastfeeding continued until the age of ~2 years, and weaning probably until 4 years of age. Supplementary foods included C 3 plants and probably animal fats and C 4 carbohydrates. A high fractionation of 4.9‰ in δ 15 N values was recognized between breastfeeding infants and adult females, perhaps reflecting episodic hyper‐protein diets in women linked to men's food provisioning during women's gestational/postpartum period. Additionally, male adults present a higher protein intake than females. Although this difference is not statistically significant with the current sample size, it could be a clue related to a sexual division in food procurement
