Imagine the child who is, and always has been, a doer. She is the one who is at your right hand as you shop, always eager for a task. Or the boy who will do the vacuuming—doesn’t mind it—and always has some new trick or feat to show you. He or she is active in physical play, and is capable of attracting a whole group of kids—in the neighborhood or on the playground—to whatever game they are playing. With a consistent pattern of stress this child can slide right into hyperactivity.
