Although this step seems extreme, it may be critical to protect children less than 5 years old who wander through the house at night without an understanding of dangers, such as fire, hot water, knives, or going outside. Send your child back to her room if she comes into your bed at night. Sternly order your child back to her own bed. If she doesn't move, escort her back immediately without any show of affection or pleasant conversation. If your child tries to leave her room again, temporarily close her door.
Some parents lock their bedroom door.
Remind your child that it is not polite to interrupt other people's sleep. Tell her that if she awakens at night and can't go back to sleep, she can look at books or play quietly in her room, but she is not to bother you. If she awakened you at night with screaming or demands, visit her briefly. Reassure her that she is safe. If she needs blankets readjusted, help her do this.
