Having complete sleep is very important for everyone but most especially for children. Sleep is the time when our body restores itself and for children's bodies to recharge and retain the information they have learned throughout the day. During deep non-REM sleep, the body's energy is restored, growth and repair occur and important brain development hormones are released. It is vital to create a cool, quiet, and dark sleep environment. It is best to stick to a consistent bedtime as well.
