Although your child may be walking around the house, he is not awake and isn't aware of what he is doing. It is not necessary to wake a child up that is sleepwalking. Instead, you should just make sure that he can't hurt himself and maybe return him to bed. If sleepwalking occurs often and you are worried about your child's safety, you can try and wake him up yourself, before the time that he typically wakes up. This treatment can disrupt the cycle and decrease his sleepwalking.

This is called bruxism and is usually not a concern, unless it is leading to damage of his teeth. Children with bruxism should be evaluated by a pediatric dentist, who may recommend a plastic mouth guard to prevent damage.
