DS has a new DS game, Cradle of Egypt... he is enjoying it, but doesn't know how to save each level as he accomplishes it.. so we are arguing.. because I say "DS get dressed please" and he says " when I have finished this level".. and then I wait, and he finishes the level but has to choose between disobeying me, or turning it off and losing the levels he has cleared so far. Guess which he chooses 
I am no techy.. but I think he is on stage 1...
Please ask any experts in your house for advise and restore peace in mine!
