Parasomnia are often more frequent in kids than in adults. Indeed, over 80% of preschool-age children experience parasomnia events. Some pyschologists associate parasmonias in young (preschool) children with separation anxiety, and most experts feel there is a genetic basis, too.

The Cleveland Clinic has a good website section on parasomnias.

Stimulas control therapy – learning to sleep right. This tries to teach the subconscious mind that at a certain time (bed time) and in a certain location (the bedroom) it is time to sleep. These ideas are good for anyone – not just those with chronic insomnia.

Avoid daytime napping
