Scores for receptive and expressive language skills, awareness of sound-word structure, literacy and early math abilities were higher in children whose parents maintained rules about going to bed at a prescribed time. Having an earlier bedtime further supported higher scores for most developmental measures.
The study involved a nationally representative sample of approximately 8,000 children that completed a direct assessment at 4 years of age. They were part of the Early Childhood Longitudinal Study, Birth Cohort.
