The ability to be still requires brain maturity. When a child cannot be still it is usually due to a lack of brain maturity. Neurodevelopmental Movement provides the proper kinds of movement to develop maturity in the basal ganglia of the brain, which is the main part of the brain responsible for the ability to be still. We intuitively understand that a healthy toddler will be in near constant motion while awake, but we expect an older child to sit still. Even though a child may seem old enough to be still, when stillness is not easy or possible for the child, it usually means that the brain requires further maturation. Once we give the brain and body the innate movements for neuro-sensory-motor development, stillness becomes possible and much more comfortable for the child.
