My younger sister does not have a problem keeping the wrist link on nor does she like to run away it is just that she has a tendance to be in her own world and once she gets focused on one thing she does think about anything eles. She is ADHD and is currently on Aderial(spelling sorry) it helps a lot I just want to take the wrist leash as a littel reminder to her not to wonder off. She is a very very smart girl and she knows what to do if she gets lost but I'm so deathly scared of losing her I just can't take the chance. She is the only thing in this world that I love with all of my being.
