I never thought of Martial Arts because my oldest participated in this and they would only take kids who had good attention.
Oh goodness, if that's their attitude you need to find a different dojo. My kids' karate sensei is incredible with inattentive little kids. It's basically a huge part of the curriculum, teaching focus and self-control. Only taking kids who already have these skills would be like only taking kids for tee-ball who are already home-run sluggers with a 50mph pitching arm. Our sensei is calm and patient and structured, and you can see the evolution in all the kids from year to year, but especially the squirrely ones. My kids do have some natural ability for self-control, but martial arts has been amazing for their focus and goal-setting. I recommend it highly.
