It's depressing enough to think that parents need some sort of remote sensors to keep track of their kids--or are paranoid enough to think they need them, anyway. Making matters worse, most of the tracking devices we've seen have a clinical or Orwellian feel to them (often both).
So if we must resort to technology to raise our children, at least the "Giggle Bug Toddler Tracker" tries to make it a little less frightening for them by turning it into a toy of sorts. Rather than sound an alarm like an air raid horn, the bug blinks its eyes and emits a "child friendly" beep, according to Red Ferret. Once the kids are returned safely, you can then begin disciplinary procedures with the "Control-a-Kid" remote.
