Consistent use of bedtime parenting strategies mediates the effects of sleep education on child sleep: secondary findings from an early-life randomized controlled trial ✩

Parents assigned to the Sleep intervention group had 63% greater odds of consistently using more bedtime strategies at 4 and 6 months compared to the Control group, and parents in the Combination grou

Effect: improvement; cumulative OR = 1.63; CI: 95% CI 1.14–2.33

Each additional bedtime strategy consistently implemented during infancy predicted a significant 3% reduction in child sleep self-control difficulties at age 3.5, and this effect partially mediated th

Effect: improvement; 0.97; CI: 95% CI 0.95–0.98

Each additional bedtime strategy consistently implemented during infancy was associated with a 0.152 standard deviation increase in trait overnight sleep duration measured by accelerometry from ages 1

Effect: improvement; 0.152 SD increase per strategy

Children of parents assigned to the Sleep intervention group had approximately 6% fewer sleep self-control difficulties at age 3.5 compared to controls, with the effect partially mediated by consisten

Effect: improvement; approximately 6% reduction

Parents assigned to the FAB-only group did not differ from control parents in bedtime strategy use, and their children did not differ from controls in sleep self-control difficulties at age 3.5, confi
