Ironically, many children are walking around with an underdeveloped vestibular (balance) system today–due to restricted movement. In order to develop a strong balance system, children need to move their body in all directions, for hours at a time. Just like with exercising, they need to do this more than just once-a-week in order to reap the benefits. Therefore, having soccer practice once or twice a week is likely not enough movement for the child to develop a strong sensory system.
Children are going to class with bodies that are less prepared to learn than ever before. With sensory systems not quite working right, they are asked to sit and pay attention. Children naturally start fidgeting in order to get the movement their body so desperately needs and is not getting enough of to “turn their brain on.” What happens when the children start fidgeting? We ask them to sit still and pay attention; therefore, their brain goes back to “sleep.”
