My friend's daughter has been kickboxing since she was 4 years old and doing some pretty intense hand to hand combat in martial arts since age 6. He says she loves it and actually begged him to sign her up. But whenever I see his daughter now 14. She's bruised up with some new injury and is obsessed with keeping her weight down! She is 5'7" tall and weighs maybe NINETY POUNDS ON A GOOD DAY! I know I can't report my friend,because he's not the one causing her injuries,but I am worried about her.Is it abuse to put your kid through this?
