Multiple Linear Regression with Standard Predictor Entry Predicting T4 Competence

	R²	p	β	(SE)	p
	.30	<.001
Intercept			3.64	(0.68)	<.001
T2 sleep problems			−.10	(.09)	.293
T2 napping behavior			.20	(.09)	.027
T1 competence			.49	(.09)	<.001
T1 child age			−.01	(.10)	.894
Child sex			−.12	(.09)	.163

Note. N = 123. T1 = baseline, T2 = 3 months post-baseline, T4 = 9 months post-baseline. Competence = Infant-Toddler Social and Emotional Assessment raw total score. Sleep problems dummy coded 0 = no parent-perceived sleep problem, 1 = a small or very serious parent-perceived sleep problem. Daily napping behavior dummy coded 0 = does not nap daily, 1 = naps daily. Child age = months. Child sex dummy coded 0 = female, 1 = male.
