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 to 5, and this mediated the Sleep intervention's effect on sleep duration.
| Effect size | 0.152 SD increase per strategy |
| Follow-up | 4-5 years |
| Comparator | Fewer consistently implemented bedtime strategies (0-4 index, continuous) |
| Effect summary | improvement; 0.152 SD increase per strategy |
