A form of child insomnia called bedtime resistance occurs when children don’t go to bed on time unless a parent or guardian enforces a bedtime. If the children are made to go to bed on time, then they tend to fall asleep at a normal hour. If they are not given strict bedtimes, then they may linger awake for hours at night.
This disorder occurs commonly in young children. Adults may also have varying bedtimes and poor sleep schedules, but this is not called child insomnia.
