There were some errors in the online version of this article, which have been corrected.

Page 3, the second paragraph (under Table 1) first sentence was incorrectly given as:

Daily MOM biomarkers were used to calculate daily values for Na and Na:K ratio, daily rates of change in Na and Na:K ratio, achievement of secretory activation (yes/no; defined as Na ::16 mMol and/or Na:K ratio <0.8), and reversal of secretory activation, defined as having at least 1 daily MOM sample with Na >16 mMol and/or Na:K ratio >0.8 on a day after achievement of secretory activation.

Daily MOM biomarkers were used to calculate daily values for Na and Na:K ratio, daily rates of change in Na and Na:K ratio, achievement of secretory activation (yes/no; defined as Na <16 mMol and/or Na:K ratio <0.8), and reversal of secretory activation, defined as having at least 1 daily MOM sample with Na >16 mMol and/or Na:K ratio >0.8 on a day after achievement of secretory activation.

Page 5, the sentence in the first line of second column was incorrectly given as:

While daily Na concentration and Na:K (Supplementary Fig. 3) was higher in LIPG than HIPG consistently (p = 0.07 for Na; 0.39 for Na:K), the differences did not warrant statistical significance most likely due to limited sample size.

While daily Na concentration and Na:K (Supplementary Fig. 3) were higher in LIPG than HIPG consistently (p = 0.07 for Na; 0.39 for Na:K), the differences did not warrant statistical significance most likely due to limited sample size.

Reference 18 was incorrectly given as:

The Funding information section was missing from this article and should have read. Study was partially funded by Medela, AG.

The original article has been corrected.
