How Can I Prevent Nightmares?Although it is normal to have a nightmare once in a while, there are some techniques you can try to get nightmares under control.
Get into a healthy sleep routine. Try to go to bed about the same time and wake up at the same time every day. Unless you're sick or didn't get enough sleep the night before, avoid naps during the day. Avoid eating or exercising just before bedtime. Avoid scary books or movies before bedtime if you think they might be causing your nightmares.
Sleep with a stuffed toy or favorite blanket. This helps some kids feel more secure.
Use a nightlight. Even if you gave up yours up years ago, you might want to turn it back on. With a nightlight, if you awake from a nightmare, you'll be able to see familiar things and remember where you are.
Keep your door open. This will help you remember that your family is close by. If you are scared, get up and find someone for reassurance. You're never too old for a hug!
