Your son is 6 and take Concerta 18mg and he is having a hard time going to bed at night how can you help him?

It is very simple. Give him 3mg of Melatonin a couple of hours before his bedtime. It is natural and sold with the vitamins. This is a chemical your body produces naturally to help you sleep. Most ADHD children use this to help promote sleep. Good Luck.

You could also try giving him 1mg of Melatonin about 30min before his bedtime. Its less drugs in the end, even though Melatonin is natural.
