Is your child restless in bed and tired during the daytime? When you go into their bedroom, do you see the sheets twisted up and the covers undone? Maybe they come into your room to complain of not being able to fall asleep or go back to sleep. They may say their legs are itchy or tickly. If so, it could be that your child is one of the approximate 2%-4% of children who may have Restless Leg Syndrome, according to The National Sleep Foundation.
