My 6 year old son has begun to develop the bad habit of wandering off too far ahead of us. He's done this a few weeks ago when we were hiking and again at the local mall. These events have begun to make me think ahead to our October WDW trip. I'm considering bringing some of those nifty walkie-talkies and giving him one with instructions on how to use it. Does anyone have advice for keeping a child unlost (or how to become found once becoming unlost is no longer an option)?
