(HealthDay News) -- Parents often wonder if children are getting enough sleep. A simple way to gauge the issue is to watch your child's behavior.
The National Sleep Foundation says warning signs of insufficient sleep include:
- Difficulty waking your child, and struggling to get moving within 15 minutes.
- Sleeping at least two hours more each night during school breaks than during the school week.
- Falling asleep at school and during brief car trips.
- Irritability, hyperactivity or other unusual behaviors.
