(teksmith)It’s every parent’s nightmare — you leave your young child in the care of someone else for a few hours, only to return and find your kid has gone AWOL. That’s what Brent Csutoras says happened to his family during a Disney Wonder cruise in January. According to Brent, he and his wife had dropped their 3-year-old son off at an on-ship childcare facility, where each youngster was fitted with an electronic wristband tracking system that should alert staff if the child wanders off and then help pinpoint the kid’s position on the ship. When Brent returned a bit later to pick his son up, he was nowhere to be found.
