DS loves the computer and always has, but since summer he's started 'gaming' in a bigger way. He's playing Ben10 games online, Kung Fu panda on the xbox, Mario kart on the wiii etc. I've been putting a limit to it as I don't think it's too healthy for a child of his age (just turned 4). However, he's recently had a few weeks of illnesses so he's played it a lot and still wants to play a lot. He's very active otherwise and does a range of activities.
Just wondering if it'll screw up his brain or something? Or give him RSI or bad eyes? How much (per day/week) do you think I should limit use to? What do others do?
