Legend
Arc requires the camera to see the controller to guage distance. It's as dependent on the FOV as Natal. As is Wiimote, which, if it's using the IR sensor to determine distance, needs to be a minimum distance from the TV.
As for kids so young they eat the controller, why even write them computer games?! Aren't there othe activities they'd rather enjoy that will be generally more developmentally focussed? If you want computer games for < toddlers, you'd really want a specialist controller with multi-material touch pads and widgets IMO.
Yes, but often they see their older siblings playing and way to "play" also. And if you don't watch them, they sometimes lose interest/forget why they wanted the controller/or whatever reason and start gnawing on the controller.
At least with Natal or something along those lines, if they see older brother jumping around waving their arms around, they'll try to do it also, even if they might be too young to do so.
Kids are a never ending adventure.
