BM, breast milk, CI, confidence interval; NBM, non‐breast milk. *Multiple linear regression with weight and length gain from month 1 to month 3 and from month 3 to month 6 as dependent variables and BM Zn intakes at months 1 and 3, NBM water intakes at months 1 and 3, infant age at months 1 and 3, infant gender, birthweight and length and infant weight and length at months 1 and 3 as independent variables. ^†Weight gain and length gain from month 1 to month 3 and from month 3 to month 6 are calculated as the difference in weight and length, respectively, during these time points. ^‡NBM water intake at months 1 and 3 is calculated using ‘dose‐to‐mother’ deuterium dilution method.
