It is possible that your child’s sleep habits might improve with an earlier bedtime. Body clocks are very sensitive to light, so it is more natural for a child to want to sleep soon after it becomes dark, and wake soon after it becomes light. Earlier to sleep doesn’t necessarily mean earlier to wake. If you think it is possible to fit an earlier bedtime into your schedule, you could use the faded-bedtime technique to gradually shift bedtime earlier.
