Absolutely!!! My son goes and goes and goes. I call him the Engergizer Bunny! The biggest question, when it comes to ADD/ADHD, is can your son focus on activities? For example, will he sit and play with his cars for 15 minutes in a row? Will he watch a short movie? If he does, then his attention span is normal and he's just all energy. Also, take a look at his diet and make sure that he's not starting the day off with a lot of sugar such as sugar cereals. And, of course, you should always mention this to your doctor if you are at all concerned with ADD/ADHD.
