Hello Jill,
Sleep is very important in the health of a child. I was reading an article that children with chronic pain are given melatonin to improve their sleep, which is a healthier approach, thus reduces their pain as well. In addition, many children nowadays do not get enough physical activities. Allowing them to play outside and more physical activities may improve their sleep.
