As a parent, you do whatever you can think of to keep your child safe. You make sure he rides his tricycle with a helmet, you strap him snugly into his car seat, and you even have your mechanic check out every unusual noise to make sure the car is safe. But accidents have a way of happening even when you take every safety precaution. And if your child suffers a head injury, he might also develop one of the many possible speech disorders in children, such as dysarthria.
