More research is needed to identify what is normal when it comes to child sleep. Some of what is known is that children need longer nighttime sleep until about 9 years old. By school age, most children sleep through the night, but children up to 3 1/2 years old continue to wake at least once. Low birth-weight and pre-term infants sleep more. Infants of younger mother sleep more. All infants sleep longer at night, wake multiple times at night, and sleep longer daytime naps than young children who mostly stop taking naps by 5 years old. Girls sleep longer than boys. Children with siblings sleep less.
