Abstract

We report that, among exclusively breastfeeding mothers at day 7 postpartum, those with milk supply concerns were significantly more likely to exhibit biochemical evidence of less progress toward mature lactation (elevated ratio of breast milk sodium to potassium concentration). Furthermore, an elevated ratio of breast milk sodium to potassium concentration was predictive of early weaning.
