Document Summary
Sleep is the main activity of the brain in the first years of life. Sleep is essential for brain development and regulation. Sleep deprivation impairs functioning of the prefrontal cortex: decreased concentration and decreased ability to inhibit or control basic drives, impulses, and emotions. During sleep, brain activity cycles between rem and non-rem sleep. In rem sleep the brain is very active, in fact it is highest during rem sleep. The waves are quiet, slow, and synchronized during nrem sleep. During rem sleep, new information is sorted and stored into memory. Sleep patterns, needs, and problems change as children develop. Infants and toddlers: waking during the night problems. Younger school-aged children: going to bed problems. Adolescents: going to , staying, or having enough time to sleep. Infants and younger children have much more rem sleep. Dyssomnias: disorders of initiating and maintaining sleep; very common. Night waking is more common in infants and toddlers. Falling asleep problems: more common among preschoolers.
