Correlation between maternal and infant cortisol varies by breastfeeding status.

ABSTRACT:

Objective

The objective of this study was to examine associations of mother and infant salivary cortisol, measured three times over the course of a day, and assess whether these varied by breastfeeding status.

Methods
