i have bought a nintendo ds lite each for my sons as chanukah presents. is it safe for them to use the multiplay function on it (which i think connects with wi-fi)?
they would really like the mario kart game for it as they have played their friends one, but i thought to save money they could share it.
But as they are only aged 4 and 6 i am a little worried if wi-fi is dangerous to young children!
