Many of you out there probably know about the wonders of melatonin already. Speaking personally, this was a lifesaver for my affected son Mason as he's had severe sleep issues since birth. A dose of melatonin in the early evening hours helped him fall asleep much faster and saved our sanity.
The only problem we found for us was that it only helped him FALL asleep. It didn't help him STAY asleep. Still at nearly 5 years of age he's not sleeping thru the night, but it's better than it used to be.
