"my son is 5 years old, he is autistic his doctor said to try melatonin. i give him 3mg at night 30 minutes later he is sound asleep. it has been great. no more fighting him to lay down. i was scared to use it, but now i know it works. he hasn&#039;t slept good since he was born. before melatonin i felt like i still had a newborn, waking up and not sleeping. i highly recommend this for autistic children, of course check with their doctor first.
