I am a special education teacher and I have 7 ADHD children in my classes at all times during the day. The students are in an "inclusion" setting where they are in a regular education classroom with other regular education students and also other Special Education children, including 1 child with Autism who has frequent outbursts and rocking. Needless to say, keeping the ADHD children on task was quite difficult. I went to a seminar about ADHD children and they discussed the Melatonin debate. There were many proponants for the melatonin dosage and many who disagreed with it. One thing I did hear ALL of them say is that it is VERY important for Doctors to screen current melatonin levels before starting any child on meltaonin. There are many problems that can arise if the child's levels are too high. Ask your doctor to screen your son and if he doesn't agree, go to someone who will. On another note, several of the mothers of my ADHD children swear by the "wombs sound and vibrate bear" to help their children go to sleep. It has a constant heartbeat sound and it has a low vibration that stimulates an ADHD child enough to aid that sensory overload that they need. Turn off the radio, dim the light to a nightlight and try it. It would be much easier than the meltanonin thing. Good luck!
