Keep an eye on your child's TV, Internet, or game-machine intake even when you aren't home. The Time-Scout Monitor plugs in between the addictive electronic device and the wall outlet, and lets you set a limit on, say, how much Nintendo Junior is allowed on a Tuesday afternoon. It begins a countdown the moment the child starts using the machine, and when the time allotment is up, the power shuts off. Unlike you, Time-Scout doesn't negotiate or ever give in to whining or tears. To buy: $90, Card Access, www.time-scout.com.
