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. Energy is the essential element in all our accomplishments. Anyone, though, who has experienced either unharnessed energies in themselves or in another knows that it can seem overwhelming.
