Objective: to search associations between plasma and breast milk cortisol and anthropometric variables in mothers with pregestational normal-weight (NW) or overweight/obesity (OW/OB) and their children at 3 and 6 months postpartum.Material and Methods: Two cross-sectional studies were conducted. Mother-child dyads were recruited at 3 (18 NW and 16 OW/OB mothers) and 6 (35 NW and 33 OW/OB mothers) months postpartum. In mothers, anthropometric measurements and cortisol levels in plasma and milk were assessed at 3 and 6 months postpartum. In children, cortisol was assessed in saliva at 3 and in plasma at 6 months postpartum, as well as anthropometric measurements. Normality of the variables was tested using Shapiro-Wilks test. The differences in plasma and breast milk cortisol levels between NW and OW/OB mothers were assessed with Student’s or Mann–Whitney–Wilcoxon test. Pearson or Spearman correlations were performed, considering significant a value of p
