What are some common sleep disorders in children?

The University of Michigan's Sleep Disorders program includes five issues that may be disruptive of good sleep practices. These include:

Sleep deprivation: As noted in the previously, the amount of sleep generally required varies with age and genetic predisposition. Unfortunately many older children, especially teens, do not receive an appropriate amount of sound sleep.
Night waking: All children after the first 7 to 8 months of life start to be more sensitive to internal and external stimuli. If an infant has not yet learned to calm himself and resettle back to sleep, the parents commonly are summoned to help the child return to sleep. This pattern may repeat itself several times each night.
Separation anxiety: Children experience this emotion commonly at 5 months of age as well as during the toddler years. Such children become anxious and are unable to enter a comfortable sleep pattern unless parents are present.
Resistance to sleep/settling problems: This occurs when your child does not want to go to bed at a reasonable time. Stalling, temper tantrums, and other resistance patterns are common. Parental persistence generally will resolve this common issue.
Parasomnias: Parasomnias are problems that disrupt sleep. Examples include night terrors, grinding of teeth, sleepwalking, etc.
