Regression Predicting 12-month Infant Cortisol Slope

Variable	B	SE	β	F-change	Δ R²
Step 1				2.60^†	.09
6-month infant slope	.13	.13	.14
6-month breastfeeding status	7.6^*	.35	.27
Step 2				5.46^*	.09
6-month infant slope	.05	.13	.05
6-month breastfeeding status	.67^†	.34	.25
6-month maternal slope	.37^*	.16	.31

Note. This model included 54 dyads. For the second step, F (3, 50) = 3.70, R² = .18, p = .02.
