My son loves soccer. He has a lot of energy. Soccer is a great way to burn it off. How many 4 year olds can run 3/4 mile without stopping. He loves to run and he is aggressive. This is not so good in school but it is awesome for sports. Most kids are afraid of contact. I am always telling him, don't knock the other kids down. He fires back quickly, "but I want the ball". I smile a little bit on the inside.
