Children in households with bedtime rules and children who get adequate sleep score higher on a range of developmental assessments, according to a research presented at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.
The study also provides a wealth of information about typical sleep patterns in 4-year-old children. According to the American Academy of Sleep Medicine, preschool children should get a minimum of 11 hours of sleep each night. Getting less than this recommended amount of sleep, the study's authors found, was associated with lower scores on phonological awareness, literacy and early math skills. The data show that many children are not getting the recommended amount of sleep, which may have negative consequences for their development and school achievement.
