Hyper-energized and hypersensitive children are at a serious disadvantage when it comes to applying the brakes because they have so much more to overcome. The brakes on a cement truck have to work much harder to stop the vehicle at 10 miles per hour than do those on a little Honda going the same speed. Another important thing to keep in mind when dealing with children is that they are still learning to apply the brakes in general. This is a major part of the developmental overlay of childhood. They aren't even close to our mature development in this department, and they certainly weren't born with any ability to control.
Babies have virtually no control at all.
If they did, there wouldn't be a diaper industry. Control is a process mastered through evolution and development. An ADHD child's inability to control his intensity and impulses is mainly looked upon as a curse. Children who are bouncing off the walls in over-energized fashions are considered by some to be a blight on society. Having a lot of energy is not a crime, however.
