Both of my boys take 1mg at night. Sometimes Kearnan needs as much as 2mg to fall asleep. My guys both have special needs and it does help them get to sleep and stay asleep. Tharen has spent the night in my bed in months (though I think his psychiatric meds are helping with that as well). Kearnan used to stay up most of the night talking to himself or complaining of the inability to fall asleep but the melatonin really helps. Kearnan is 11 and 73lbs, Tharen is 7 and 40lbs if that helps for dosing.
