I have a 5-year-old who still does not sleep all night regularly. Lately she has been waking multiple times a night, and dh and I are about at our wits end. We also have an 11-month-old baby who still, obviously, wakes. My mom was telling me about a friend of hers whose daughter, about the same age, has ADHD and had a really difficult time sleeping, and they were giving her melatonin shortly before bed. Supposedly the melatonin has made a HUGE difference. My dd sounds a lot like this girl in terms of behavior, and I wouldn't be surprised if my dd were at some point to be suspected or labelled as having ADHD. But regardless of the source of the issues, I was wondering if anyone out there has tried melatonin for helping a child to sleep? Did it work? How much would you give? Are there any side effects or potential risks I should know about?
