Why so many kids can’t sit still in school today
When compared to children from the early 1980s, only one out of twelve children had normal strength and balance.
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.
